| Product Name | 1,3-Dioxolane |
| IUPAC Name | 1,3-Dioxolane |
| Chemical Formula | C3H6O2 |
| CAS Number | 646-06-0 |
| Synonyms & Trade Names |
Dioxolane; Methylenedioxyethane; 2,2'-Methylenebis(oxirane) (used in some custom programs); Application-relevant trade names depend on downstream formulations and target solvent blend. |
| HS Code & Customs Classification |
HS Code selection follows regional rules. For most applications, 1,3-dioxolane is classified under: 2932.99 (heterocyclic compounds with oxygen hetero-atom(s) only, not elsewhere specified). Customs codes may differ if supplied as a formulated solvent blend, or in specialty grade packaging. Manufacturer provides support for local customs HS clarification if specifications or grade definitions alter classification. |
Choosing the correct identification and customs classification supports clear chain-of-custody and compliance with both chemical substance regulations and commercial procedures. Category assignment (HS code) follows the heterocyclic compound logic under global tariff schedules; confirmation depends on the declared use and product purity grade. For industrial production, the chemical formula C3H6O2 remains constant, but minor co-distillation and impurity patterns arise based on process route and feedstock control.
As a solvent raw material, dioxolane naming in documentation aligns with application—reagent supply contracts, pharmaceuticals, specialty coatings, or battery electrolyte synthesis each drive specific nomenclature, including proprietary blend aliases where customer processes demand tailored confirmation blenders. Synonyms must be matched to shipment paperwork to support regulatory traceability and minimize hold-ups at customs clearance.
HS code correctness must consider the end use. Inaccuracies in documentation can cause border clearance difficulty or flag for regulatory review, particularly where product grades meet dual-use export triggers. Ongoing industry changes in customs listings sometimes produce regional variance. Manufacturer teams communicate directly with logistics and compliance partners to verify each consignment against the latest published customs schedules.
For end users, clear and technically grounded identification details speed specification review, regulatory registration, and batch-to-batch record keeping. Only with verified source data can customers maintain traceability and meet internal and external audit demands, especially when the downstream application is subject to elevated scrutiny for purity or labeling.
In plant-scale production, 1,3-dioxolane exits the final purification stage as a clear, low-viscosity liquid. It gives off a mildly ether-like odor. Visual inspection under controlled lighting reveals no suspended solids or haze when produced to electronic or battery grade requirements. Color intensity and threshold odor will reflect grade and raw material purity, especially in custom solvent or pharmaceutical grades. Freezing and boiling transitions depend on impurity profile and water content, both closely tracked during quality control sampling.
In tightly closed, properly lined vessels, 1,3-dioxolane demonstrates reliable chemical stability well beyond standard warehousing timelines, provided exposure to acids or strong oxidants is excluded. Moisture-sensitive and acid-catalyzed ring-opening can occur if storage or transfer systems introduce traces of corrosives, necessitating ongoing checks of storage tank lining and maintenance of basic pH in ancillary lines.
Our technical teams routinely prepare aqueous and non-aqueous solutions of 1,3-dioxolane to customer specification. Water solubility and hydrophilic/hydrophobic behavior vary slightly by grade—ultra-dry requirements for electrolytes demand dedicated drying and inert handling, while basic industrial grades tolerate moderate water loads. Solubility tests guide both final quality control and shipping tank selection.
| Parameter | Electronic/Battery Grade | Industrial Grade | Pharmaceutical Grade |
|---|---|---|---|
| Purity (% min) | Determined by application | Based on order spec | Client/Pharmacopeia |
| Water Content | Ultra-low | Controlled to process needs | Low/Defined |
| Acidity/Alkalinity | Neutral | Mild variations allowed | Pharmacopeia spec |
| Color (APHA) | Extremely low | Specification guided | Regulated |
Final specification table is reviewed for every campaign to match client QA, with release according to our internal and customer-provided test protocols.
Each batch is characterized for specific residuals including aldehydes, glycols, and stabilizer/catalyst carryover. Most batches rely upon GC-MS and NMR tracking, especially with new raw material lots or during process changes. Acceptable impurity levels are capped by grade, end-use, or internal risk assessments, and root cause investigations are conducted for any outlier finding.
Depending on destination market, quality assessment includes internal SOPs based on international test standards (GC, KF titration, UV-Vis, etc.). Data collection is reinforced with regular external proficiency calibration, supporting full traceability for regulated market distribution.
The process begins with selection of ethylene glycol and formaldehyde or their equivalent precursors. Raw material purity, consistency, and supply security drive vendor and batch acceptance. Materials from alternate suppliers are qualified with full lab and pilot-scale validation, particularly for specialty end-uses.
1,3-Dioxolane synthesis typically employs an acid-catalyzed condensation. Catalyst type—mineral acid or solid acid—affects not only product formation rate but also impurity spectrum. Temperature and stoichiometry are tuned for batch yield and downstream product specification. Byproduct minimization remains a primary production concern at scale.
Each process line operates with continuous monitoring of reaction temperature, pressure, water removal, and catalyst presence. Post-reaction, crude product passes multiple distillation columns for removal of high-boiling, low-boiling, and azeotropic impurities. Frequently, activated adsorbent beds polish final product targeting end-user color, odor, and moisture specs.
QC checks align with process control data and final product samples, scored against the agreed QA/QC release criteria. Batches are released only when key metrics (GC area %, moisture content, color, odor, density) meet spec and retain within-batch reproducibility. Out-of-spec material is reprocessed or downgraded following internal protocols.
1,3-Dioxolane actively participates in ring-opening polymerizations and acetal-exchange reactions, forming a backbone for polyacetals and certain electrolytes. As a labile ether, reaction control focuses on acid/base sensitivity, especially in downstream pharmaceutical and battery-related syntheses.
Catalyst type and reaction solvent selection depend on intended downstream chemistry. For controlled polymerizations, operators tightly regulate temperature and solvent dryness, since trace acid or base can trigger unwanted side reactions or rapid degradation.
We support further chemical transformation into protective groups for carbonyls, functional solvent blends, and electrolyte intermediates. Downstream product purity and yield depend on the removal of stabilizers and ability to tailor solution phase properties during post-processing.
Plant engineering recommends sealed, nitrogen-blanketed storage at moderate temperatures for best shelf life. Operator logs verify tank integrity, and desiccant systems prevent water ingress for high-purity grades. UV exposure control prevents long-term yellowing or instability in sensitive markets.
Bulk storage requires lined tanks or specific alloy construction due to potential for material attack by trace acids or moisture. Product containers undergo regular inspection for corrosion or pitting. Smaller volumes use chemically compatible HDPE or fluoropolymer drums where solvent leaching is a concern.
Shelf life depends on grade, storage conditions, and packaging. Higher water, acid, or aldehyde content reduce time before measurable yellowing or odor development. For high-end uses, periodic inventory retesting allows timely intervention upon early degradation signs.
Labelling aligns with current GHS guidance for flammable and irritant organic solvents. Regulatory hazard and precaution statements feature on all shipping documentation per jurisdiction.
Operations maintain local exhaust in filling, transfer, and blending zones to minimize vapor inhalation risk. Explosive atmosphere controls, including inerting and static minimization, govern handling. SDS documentation underpins PPE and response protocols for fire, spill, and exposure scenarios.
Technical teams adhere to industry-standard guidance for permissible exposure limits, leveraging ventilation and personal monitoring as batch volumes increase or task duration extends. Training for operators emphasizes rapid detection of off-odors, leak signals, and process upsets. Decontamination and emergency response equipment is stationed at high-usage points on site.
1,3-Dioxolane output depends on the reliability of upstream ethylene glycol and formaldehyde, as both are primary feedstocks. Availability varies with fluctuations in these upstream markets. In continuous production, shutdowns for maintenance or unexpected process disruptions can impact both batch and campaign capacity. Reactors assigned to pharma and electronics grade products require more stringent cleaning and validation routines than standard industrial grades, affecting total yearly output. Inventory strategies rely on forecasts for solvent, polymer, and battery electrolyte segment demand.
Lead time fluctuates with plant loading and the complexity of customer specifications. Higher-purity or custom-packaged lots take longer due to extended quality checks and specialty filling requirements. MQ varies, but bulk industrial customers typically order isotainer or drum-scale quantities. Shorter lead times may be possible for off-the-shelf inventory, though specialty or pharma-grade material will extend the fulfillment window.
Drums and IBCs are standard for most downstream segments. Battery grade and electronics applications increasingly specify aluminum-lined drums or composite containers to minimize risk of contamination. Pharma and semiconductor operations often demand double-sealed, tamper-evident containers. Container type directly affects in-transit risk management and should align with solvent sensitivity to air and moisture exposure. Packaging is not just customer-driven but also influenced by regulatory mandates in regions such as the EU and Japan.
Most consignments move under EXW, FOB, or CIF incoterms, subject to negotiated credit terms for established buyers. Regulatory frameworks in destination countries limit shipping windows due to classification as a flammable liquid. Some ports impose access restrictions or require special labeling in the SDS/transport paperwork, which can delay customs clearance times. Container turnarounds and verification at intermediate storage facilities create additional time constraints on shipments bound for regulated industries.
Raw material input cost for 1,3-dioxolane centers on market indexes for ethylene glycol and formaldehyde. Regional price movements in natural gas and crude oil ripple down to these inputs; for example, tighter gas markets in Europe make glycol sourcing more expensive. Plant utilities—especially steam and electricity—can account for a significant part of the conversion cost, and any sudden price spike in local energy tariffs triggers near-term product cost increases.
Grade-driven pricing reflects the purification burden: battery and pharmaceutical purities require multi-stage distillation, higher waste handling, and more stringent in-process testing. Each increment in purity specification adds not only analytical costs but also impacts batch acceptance rates. Packaging compliance for UN-certified containers or custom seals further separates price points between applications. Contracts specifying traceability certificates, CoAs, or special shipping documentation incur additional administrative and validation overheads, which get factored into final quotation structures.
Annual global demand for 1,3-dioxolane is shaped by fluctuations in lithium battery, agrochemical, and electronics sectors. Major supply clusters operate in East Asia, Western Europe, and North America. Export patterns shift in response to national policies on hazardous substance logistics and the pace of electrification projects.
United States and Europe both emphasize high-purity grades for battery applications, and stricter end-user audit regimes shape supplier qualification timescales. Japan maintains leading purity standards in solvent and semiconductor applications. India and China ramp up bulk production capacity, especially for the battery manufacturing chain, driving occasional overcapacity-induced price compression—yet these markets remain exposed to feedstock price volatility and environmental compliance crackdowns, which can temporarily tighten output.
Forward price forecasts for 1,3-dioxolane reflect expected increases in raw material and compliance costs, especially if upstream glycol or formaldehyde experiences sustained tightness or if energy transition-related feedstock changes impact input pricing. Demand-side, the battery sector's expansion in Asia is projected to offset slower growth in mature markets. Pure grade 1,3-dioxolane is likely to command a rising premium over technical grades as end-use requirements become more sophisticated and downstream audit rigor deepens. Commodity-grade prices may see periods of competition-driven pressure but remain sensitive to input and regulatory factors through 2026.
Price trend references, supply-demand statistics, and regulatory updates draw on government trade bulletins, public procurement data, and major chemical market analysis agencies. Internal benchmarking relies on batch production records, raw material purchasing contracts, and quality release logs calibrated against final customer acceptance rates.
Lithium battery segment growth in East Asia motivates both capacity expansions and technical upgrades to ensure low-moisture, low-ion trace contamination grades. European chemicals regulations aiming at stricter VOC controls push manufacturers to invest in containment and recovery infrastructure. Global disruptions to methanol and formaldehyde supply chains translate quickly into cost pass-throughs and, in turn, reallocation of output to higher-margin end-markets.
New or updated framework in the EU (REACH), US (TSCA), and parts of Asia mandates data transparency for impurities, emission controls, and in some cases, dedicated logbooks for batch traceability. Downstream audit requirements from automotive and electronics sectors now extend into solvent sourcing, handling, and documentation, prolonging vendor approval windows. Environmental compliance enforcement in China prompts periodic supply tightening—manufacturers in other regions sometimes face increased inquiry and qualification demand as a result.
Plants adapt by increasing investment in analytical control, deploying on-line purity monitoring for rapid in-process adjustments, and diversifying feedstock sourcing to buffer against abrupt upstream cost spikes. Internal cross-functional teams reevaluate audit preparation, documentation standards, and waste minimization practices—especially where downstream users enforce stricter carbon or traceability reporting.
1,3-Dioxolane serves as a core intermediate and solvent across multiple industrial processes. In battery and energy storage, manufacturers value its solvating power for electrolytes. Synthetic resin plants incorporate it during polymerization stages, especially for polyacetal processing, due to its compatibility with acetal monomers. Specialty coatings, adhesives, and certain pharmaceuticals utilize 1,3-dioxolane either as a process solvent or a chemical building block. Each field imposes distinct purity, water, and residue content demands. Our sales and technical support teams review each application’s critical parameters before recommending a grade.
| Application Field | Recommended Grade | Key Performance Requirement |
|---|---|---|
| Electrolyte Solvent (Lithium/Secondary Batteries) | Battery/Electronic Grade | Low water content, metal impurity control, stringent peroxide residue limits |
| Resin/Polyacetal Manufacturing | Industrial Grade | Residue solvent impurity monitoring, peroxide formation control, consistent boiling range |
| Pharmaceutical Intermediate or Solvent | Pharma Grade or Custom Specification | Pesticide residue compliance, tight control of trace organic impurity, review of extractables profile |
| Specialty Coatings and Paints | Technical or Industrial Grade | Odor threshold, color stability, peroxide content testing |
Process solvent applications often focus on controlling water content, as excess moisture disrupts lithium salt dissolution or influences polymer yields. In battery sectors, metal ion trace analysis becomes mandatory, as sodium or iron ions can reduce cycle life. Purity thresholds differ: battery producers frequently reject lots outside narrow ppm limits, while resin companies prioritize consistency in boiling point and low peroxide. Pharmaceutical and fine chemical users require batch-specific impurity profiling, supported by additional chromatographic testing not always standard for technical grades.
Start by documenting the technical role 1,3-dioxolane will perform. Solvent, monomer, intermediate, or extraction aid functions each call for different specifications. Nameplate applications in battery manufacturing demand full disclosure of downstream formulation constraints.
Ascertain any regulatory or customer-specific requirements before finalizing grade selection. Food contact, pharmaceutical synthesis, or export to certain regions can introduce additional compliance challenges. Our technical department checks every regulatory file provided by the customer, cross-referencing REACH, TSCA, and region-specific safety datasheets.
Each user group benchmarks purity in their own way. Speak with your quality and process teams about critical impurity thresholds—especially for water, alcohol, and peroxide content. For research and specialty formulators, request third-party impurity analysis if the application warrants it.
Laboratory users may only require kilogram-scale, while processors or plant operators request drums or bulk ISO tanks. Higher grades, especially those with additional purification demands, affect overall raw material budgets. We maintain traceable logs for every batch and advise early engagement for projects above routine scale, to guarantee supply continuity.
Before finalizing commercial orders, request a representative sample under controlled shipping and storage. Validate the batch against your lab’s analytical standards and run pilot tests within your real process environment—particularly for moisture- or impurity-sensitive end uses. For new or highly regulated applications, provide feedback from your validation campaign so technical adjustments may be considered upstream.

As application trends change or logistics landscapes shift worldwide, we continue to review inventory management and just-in-time production approaches. We remain open to discussing schedule alignment, but always within the realities of factory workflow and safe chemical handling.
For technical advice or to discuss requirements that differ from our standard MOQ, our technical and commercial teams coordinate to provide practical recommendations grounded in real plant capabilities. Our reputation rides on every drum we fill, which shapes our approach to every production run.
In our experience producing 1,3-Dioxolane at scale, the topic of packaging, storage, and transport is a daily operational reality—not just a regulatory checkbox. 1,3-Dioxolane is a colorless, volatile organic solvent that stands out for its flammability and ability to form explosive peroxides if mishandled. Because we manufacture, store, and ship large volumes around the world, we pay close attention to safety protocols and compliance with evolving international standards.
Our standard packaging uses UN-certified steel drums or intermediate bulk containers specifically rated for flammable liquids. Polyethylene or similar plastic drums do not offer the solvent resistance and strength required for safe transport, especially by sea or air. Each package is pressure-tested, leak-checked, and clearly labeled according to the Globally Harmonized System (GHS), including hazard pictograms, UN number, and proper shipping name according to UN 1165.
Asia, Europe, and North America all retain strict requirements for packaging flammable organic solvents. A marked difference between local standards and international transport regulations (IMDG, IATA) can complicate logistics, so harmonized labeling and regular staff training avoid delays and mismatched documentation at customs or ports.
Our storage facilities operate on principles that go beyond simply locking a product in the warehouse. 1,3-Dioxolane demands strict segregation from sources of ignition and oxidizing agents. We fit our storage tanks with nitrogen blanketing and maintain a cool, dry environment away from direct sunlight. Routine sampling detects any sign of peroxide buildup, which can happen with prolonged storage. When peroxide levels exceed recommended safety limits, we treat or dispose of the product following hazardous waste protocols.
We also equip our warehouses with forced ventilation and explosion-proof lighting, underpinned by strict no-smoking policies and regular staff hazard training. Local fire codes and insurance requirements drive our investment in automatic fire suppression and spill containment systems. Ignoring these not only puts staff at risk, it attracts regulatory fines and delays plant operations.
Shipping 1,3-Dioxolane involves navigating a matrix of international regulations—IMDG for sea, IATA for air, and ADR for road transit across Europe. Our shipping department prepares full documentation, including Safety Data Sheets (SDS) updated to the latest regulatory revisions. Every shipment leaves our factory traceable and compliant, monitored until receipt at the customer’s site. We use only calibrated and validated packaging, and never cut corners with non-certified or refurbished drums.
As regulations update, we invest heavily in training logistics staff to avoid transport incidents, which safeguard not only our cargo but the communities along every transit route. In our operations, excelling at safe transport is never negotiable, and every major customer audit checks not only our paperwork, but our real-world compliance at every shipment and storage site.
Increasing pressure from authorities on flammable liquid handling led us to upgrade our packaging lines for complete drum integrity testing. We also established regular peroxide monitoring and more frequent change-outs of stored product. In supply chain disruptions where storage times extend unexpectedly, these measures prevent safety events and product degradation.
For partners and regulators, seeing the inside of our operation—our investment in safe storage, up-to-date packaging, and responsible shipping—provides assurance that we treat chemical safety as a daily priority, not a marketing slogan. Maintaining trust relies on doing things the right way, batch after batch.
