Product Name Fluoroethylene Carbonate IUPAC Name 4-fluoro-1,3-dioxolan-2-one Chemical Formula C3H3FO3 CAS Number 114435-02-8 Synonyms & Trade Names FEC, Ethylene carbonate, monofluoro derivative HS Code & Customs Classification 2932 99 9090 (Chemicals containing an unfused heterocyclic ring)

Commentary from Technical and Production Departments Selection of C3H3FO3 as a battery-grade additive depends heavily on intended electrochemical performance, water content, and impurity management. Commercial runs differentiate based on trace metal requirements and solvent compatibility, often referenced in downstream lithium-ion cell production. Raw materials must be screened for both halide contamination and peroxide-forming side products. Sourcing monofluoro precursors often runs into inconsistencies owing to variable upstream fluorination purity. In batch processing, reaction conditions such as temperature ramp rates, solvent polarity, and moisture exclusion define impurity profiles. Continuous runs offer better batch-to-batch reproducibility, though endpoint monitoring must address variable oligomeric byproduct loads. Custom grades requested by cell manufacturers show considerable variation in hydrolytic stability and particle residue requirements. Typical values for hydrolyzable fluoride content, high-purity carbonates, and non-volatile residue depend on both plant capabilities and customer feedback from battery pilot tests. The IUPAC naming and CAS registry eliminate sourcing confusion and simplify customs clearance under HS code 2932. Regulatory and logistical documentation aligns strictly with underlying process controls and internal standard operating procedures. Storage and shipping of fluoroethylene carbonate must account for moisture control and potential reactivity with strong bases or metal oxides. Final QA batch release includes multiple water content checks, and residual solvent profiles are verified according to end-user technical specifications.

Technical Properties, Manufacturing Process & Safety Guidelines

Fluoroethylene Carbonate (FEC): Industrial Commentary

Physical & Chemical Properties

Physical State & Appearance

Fluoroethylene carbonate is encountered as a colorless or very pale yellow liquid in most industrial settings. Faint, sharp odors can occur in higher purity product or after exposure to elevated temperatures. Melting and boiling point ranges depend strongly on grade and purity, as residual water and trace byproducts shift phase behavior.

Bulk density and viscosity both trend with purity and temperature—important for large-volume transfer and formulation. FEC forms well-wetted phases with common aprotic solvents used in lithium-ion battery electrolytes; careful drying is kept a priority during storage and blending to avoid hydrolysis.

Chemical Stability & Reactivity

Fresh FEC shows resistance against slow decomposition under argon and at ambient temperatures. Reactivity with nucleophiles, moisture, and reducing agents increases once containers are opened or when solutions are prepared. Storage stability is sensitive to oxygen and light, requiring inert-gas blanketing for long-term preservation. Stability also depends on headspace control and the absence of base or metal catalyst contamination.

Solubility & Solution Preparation

FEC dissolves easily in carbonate solvents and polar aprotic matrices, facilitating use in electrolyte recipes for Li-ion cells. Solubility is reduced in water, but not negligible—hydrolysis during solution prep is mitigated by using anhydrous solvents and maintaining a dry atmosphere in the blending operation. Solubility in each system must be validated for specific customer use cases.

Technical Specifications & Quality Parameters

Specification Table by Grade

FEC carries grade distinctions based on residual water content, organic byproducts, and ionic impurities. Exact specifications are shaped by customer requirements for Li-ion battery electrolyte, pharmaceutical intermediate, or fine chemical use. Ranges for main assay and key impurity profiles follow both internal batch data and external standards where available.

Typical Parameter	Electronic Grade	Industrial Grade
Main Assay	High, near theoretical	Grade dependent, varies by application
Water Content	Minimized, internal target applied	Depends on process route
Color (APHA)	Pale, controlled	Grade dependent
Metal Impurities	Low, monitored for battery use	May be higher, not always specified

Impurity Profile & Limits

Each production route results in characteristic trace organics and inorganics—including partially fluorinated byproducts, diols, or halide residues. Analytical programs target the detection and trend analysis of known high-risk impurities, such as unreacted starting ester, main byproduct diols, and halides. R&D and Quality groups define maximum acceptable limits based on downstream sensitivity, especially in high-energy battery manufacturing.

Release limits are harmonized with both customer requirements and process capabilities. Trace impurity identification uses GC, LC, and ICP method suites, with frequent method validation tied to lot trends.

Test Methods & Standards

Test methods derive from established industrial standards where available and are subject to ongoing review. Karl Fischer titration, GC with internal standard quantitation, and colorimetric halide assessment provide routine oversight. ICP-OES or ICP-MS may be used when parts-per-billion level metal control is required. Users with special requirements should communicate specific needs for custom method development or certification.

Preparation Methods & Manufacturing Process

Raw Materials & Sourcing

Key starting materials include ethylene carbonate, fluorinating agents, and suitable catalysts. Supply chain qualifications address contaminant background—particularly metals and halide traces—which directly affect impurity profile in the finished product. Where electronic grade purity is essential, raw materials require additional pre-treatment or certification.

Synthesis Route & Reaction Mechanism

Primary synthesis routes operate by controlled fluorination or transcarbonation of ethylene carbonate precursors. Choice of route depends on cost structure, target impurity profile, and waste handling discipline. Selection of homogeneous versus heterogeneous catalysis impacts process safety and workup efficiency.

Reaction mechanisms involve nucleophilic substitution or ring-opening sequences, with byproducts dependent on water, temperature, and catalyst loading. Intermediate species must be closely monitored, as side reactions can elevate problematic contaminants if process conditions drift.

Process Control & Purification

Key control points—temperature, moisture exclusion, staging of reactants—determine batch consistency. Process drift manifests in off-spec color or higher byproduct levels. Process Analytical Technology (PAT) tools provide in-situ verification of endpoint before downstream purification.

Distillation, extraction, and adsorption are the primary purification steps. For electronic grade, advanced filtration and multiple-stage drying are adopted to minimize residual water and soluble ions. Batch records capture all process changes and deviations as part of traceability and continual improvement.

Quality Control & Batch Release

Final batch release hinges on specification conformance for main assay, color, water content, halide level, and trace metal content, according to grade. Quality Control retains representative retain samples from each lot for shelf life and complaint investigation. Out-of-trend behavior triggers root cause review before shipment.

Chemical Reactions & Modification Potential

Typical Reactions

FEC participates in selected nucleophilic and electrochemical reactions due to its strained carbonate ring and fluoro functionality. Battery-grade FEC is valued for SEI-layer formation on graphite anodes, displaying selective reactivity at low voltage during first charge. FEC may also undergo ester hydrolysis, ring cleavage, or fluoroalkylation under suitable conditions.

Reaction Conditions

Sensitive reactions depend on temperature, catalyst presence, and exclusion of moisture. For specialty derivatizations, inert atmosphere and dry solvents are essential. Downstream use in electrolytes requires confirmation of FEC stability and minimal unintended polymerization during cell preparation.

Derivatives & Downstream Products

Modifications yield functionalized carbonates, fluorinated ethers, and specialty esters. Interest continues in step-growth polymer intermediates and fluorinated materials development. The diversity of application depends on the willingness to trace new side reactions and verify purification strategies for unique byproducts.

Storage & Shelf Life

Storage Conditions

Maintaining product quality demands cool, dry, and oxygen-free storage for most grades. High-purity FEC is stored under inert gas to avoid water pickup. Warehouse temperatures are managed to control viscosity and assess risk of container deformation.

Container Compatibility

Compatible materials include high-density polyethylene, fluoropolymer-lined steel, and amber glass for small packs. Metal containers must be passivated or lined, as corrosion or catalytic decomposition may initiate from exposed surfaces. Shelf life aligns with headspace control and absolute exclusion of light, especially for battery-application stock.

Shelf Life & Degradation Signs

Shelf life is not assigned a universal value; it depends on the packaging integrity and environmental controls. Off-color, visible phase separation, or unexpected odor represent degradation and prompt retesting before use. Quality holds reserve samples for re-examination prior to critical application.

Safety & Toxicity Profile

GHS Classification, Hazard & Precautionary Statements

FEC falls under hazardous chemical category for both acute and delayed health effects according to GHS. Common concerns relate to toxicity upon inhalation, possible skin and eye irritation, and the potential for environmental hazard due to fluorinated moiety breakdown. Shipping and handling documents specify primary hazard codes applicable to the grade.

Toxicity Data

Available data indicate the requirement for minimized occupational exposure, as long-term effects are not fully defined—especially in high-volume battery plants. Inhalation and dermal limits are set by national regulatory bodies where product is produced or imported. Where animal or in-vitro toxicity thresholds are not established, strict local exhaust and PPE requirements are enforced.

Exposure Limits & Handling

Workplace exposure limits follow both international and in-house OEL targets for volatile organic carbonates and fluorinated chemicals. Manufacturing teams maintain closed handling systems and perform regular health screening for workers with repeat exposure. Emergency response protocols cover containment, skin decontamination, and medical evaluation routes.

Appropriate training, documented procedures, and periodic refresher drills reduce risk during bulk transfer, vessel cleaning, and waste treatment. End users must request detailed safety data to match their regulatory environment and downstream safety documentation needs.

Supply Capacity & Commercial Terms for Fluoroethylene Carbonate

Production Capacity & Availability

The output volume of fluoroethylene carbonate directly tracks upstream raw material sourcing and purification reliability. Plants with dedicated production lines for battery electrolyte additives hold an advantage in supply consistency, as feedstock interruptions or purification bottlenecks drive sporadic shortages. Production run size adapts to active contracts, but off-the-shelf stock remains limited given the material’s sensitivity to environment and shelf-life constraints. Custom synthesis timelines stretch with increasing purity and application-specific impurity limits, especially when low metal content is required for lithium-ion battery use.

Lead Time & Minimum Order Quantity (MOQ)

Lead times depend less on order size and more on specific grade and packaging. General industrial grade for non-electrochemical applications often ships in bulk from ongoing campaigns, where MOQs may drop. Ultra-high-purity grades for battery, pharmaceutical, or research applications require advance reservation. Manufacturing lot release rests on full batch validation, extending dispatch if further purification or retesting is needed by the customer’s QA. Standard MOQ for laboratory and pilot-plant customers typically starts higher for export shipments due to packaging and logistics compliance.

Packaging Options

Industry most often requests fluorinated carbonates in metal, fluoropolymer-lined, or glass containers, with the packaging route heavily influenced by grade, customer receiving procedures, and the transit distance. For battery materials, product is packed under inert atmosphere in sealed drums or cans with strict moisture and light safeguards. Bulk customers may receive material in reusable tanks for closed-loop systems, reducing risk and ensuring traceability. Secondary containment and anti-tamper features are part of most export shipments, with traceable seals and serial recording.

Shipping & Payment Terms

Shipping route depends on regulatory classification. Battery-grade and bulk shipments typically follow hazardous goods protocols with certified carriers, as compliance with international lithium-ion supply chain regulations drives routing and paperwork. Payment schedules align to risk profile of the transaction; standard terms for established accounts, but advance payment or escrow may be required with new partners, especially outside local currency zones. Pre-shipment quality documentation, including COA and MSDS, ships in advance for customer import licensing.

Pricing Structure & Influencing Factors

Interpretation of Raw Material Cost Composition

Raw material cost splits originate from base monomer—ethylene carbonate or derivatives—and specialty fluorinating agents. Reagent grade, handling safety, and purification grade drive most of the cost differential, with route selection (direct fluorination versus electrochemical fluorination) impacting both raw cost and downstream waste processing. Purity improvement steps and impurity removal push up the final price, as downstream users pay a premium for low-water, low-metal lots. Batch-run yields fluctuate on raw input quality, and process deviation leads to higher rework rates and cost pass-through.

Fluctuation Causes

Raw material prices for fluoroethylene carbonate move with global fluorspar, hydrofluoric acid (HF), and ethylene carbonate supply. Regulatory events, plant outages at major upstream HF suppliers, and logistics pinch points (notably for export through sensitive ports in China) frequently cause cost spikes or allocation. Geopolitical factors such as export restrictions, anti-dumping tariffs, and energy price movements cascade straight through to manufacturing and final price. Spec tightening by downstream battery customers pushes suppliers to recalculate cost structure for higher-purity lots due to yield penalty and longer campaign runtimes.

Product Price Difference Explanation

Each purity grade commands a material price difference—battery-grade fluoroethylene carbonate is tested for moisture, total metals, and residual fluorides far beyond standard industrial grade. Reagent content, packaging type, independent lot certification, and traceability as demanded by OEM customers add further increments. Packaging in UN-rated drums or under nitrogen adds cost, as does each increment of purity certification, due to additional analytical protocols and longer in-process hold times. In the absence of explicit customer test standards, manufacturers set prices based on closest industry norm for the market application in question.

Manufacturers choose this compound to address anode interface stability and enhance cycling life, especially in high-energy density systems. Pure FEC grades support the requirements of battery cell producers using advanced graphite or silicon-based electrodes. In alternative energy storage, including solid-state batteries, cell assembly specialists rely on tailored FEC grades for specific compatibility and performance targets. Other customers investigate FEC for specialty polymers and electronic chemicals, where downstream hydrolysis reactivity and byproduct formation become critical.

Grade-to-Application Mapping

Grade	Primary Application	Key Parameters	Main Points Affecting Selection
Battery Grade	Lithium-ion battery electrolyte solvents	Purity, water content, HF content, trace metals	High purity and low moisture crucial for interface formation in battery cells. Trace halide control affects cycle stability and cell impedance. Selection process involves cross-checking with downstream electrolyte QC.
Electronic Grade	Electronic chemicals, specialty reagents	Ultra-low metals, specific organic residuals profile	Chemical processing routes and packaging are adjusted to align with device fabrication needs. Metal ion content is the focus due to contamination risk in microelectronic components.
Industrial Grade	Polymer synthesis, research, non-battery intermediates	Total acid value, residual precursor, color	Batch-to-batch consistency monitored for downstream reactivity and impurity carryover in non-energy-storage applications. Color and acidity often define grade acceptance for these users.

Key Parameters by Application

• Lithium-ion Battery Electrolytes: Water and HF levels below critical thresholds prevent rapid cell degradation. Anhydrous processing and packaging run under dry-room or inert conditions to preserve specification. Downstream performance checks hinge on compliance with customer-supplied acceptance criteria, often stricter than general chemical reagent standards.
• Electronic Chemicals: Metal ions—even at sub-ppm range—interfere with device performance. Electronic grades demand routine internal checks for alkali, alkaline earth, and transitional metal presence. In-process filtration and purification focus on trace contaminant removal to match semiconductor fab protocols.
• Polymer/Research Use: Broader impurity tolerance is common for non-battery intermediates. Color stability and precursor residuals gain attention in synthesis routes sensitive to basic or acid-sensitive catalysis.

How to Select the Right Grade

Step 1: Define Application

Selecting the grade starts with the end-use requirement. In lithium battery production, strict control of trace contaminants impacts cell reliability and warranty. For electronic chemical blending, even minor residuals disrupt device yields. Industrial synthesis typically allows for wider impurity envelopes but still demands baseline consistency.

Step 2: Identify Regulatory Requirements

Regional directives or voluntary compliance standards may require specific documentation or third-party certifications. For example, Europe and North America expect adherence to REACH or TSCA, respectively. These define allowable impurity thresholds, labeling, and transport constraints. Certain battery customers request documentation on chemical origin and batch traceability to satisfy external client or audit requirements.

Step 3: Evaluate Purity Needs

For any application, decision-makers check the role of FEC in their process. If used in a closed battery system, select high-purity, low-moisture grades to avoid shortened cell lifespan. Semiconductor-related or laboratory settings drive purchasing toward ultra-pure, low-metal specifications. Broader chemical processing enables more leeway but technical discussions with our team help confirm if lactose, aldehydes, or specific byproducts may interfere downstream.

Step 4: Consider Volume & Budget

Production scheduling and grade selection reflect available packaging formats, monthly demand, and targeted inventory turn. For volume commitments, integrated supply with stable packaging (drums, totes, or ISO containers) reduces cross-contamination and exposure risks. Lower-volume research or pilot operations rely on smaller lots, sometimes from multi-purpose lines, which can bring a broader impurity fingerprint at a favorable price point.

Step 5: Request Sample for Validation

Each batch undergoes quality release based on control samples, in-process tracking, and customer-required test parameters. Validation samples allow end users to check conformance in their unique equipment, especially for proprietary or tightly-specified recipes. Results from these tests help narrow the grade and lot needed, with the technical team available for detailed COA and batch review during qualification.
