99.5% Diethyl carbonate CAS 105-58-8 DEC

Certificate of Analysis-COA 

 Applications 

1. For Lithium Battery Electrolytes: Diethyl carbonate (DEC, CAS 105-58-8) is a widely used linear carbonate co-solvent in lithium-ion battery electrolytes, lowering viscosity and improving low-temperature performance when blended with cyclic carbonate solvents such as EC.

2. For Green And Eco-Friendly Solvent Applications: With low toxicity and good biodegradability, DEC serves as a greener solvent for coatings, nitrocellulose lacquers, inks and cleaning formulations, helping formulators reduce environmental impact in industrial processes.

3. For Chemical Synthesis And Derivatives: Diethyl carbonate acts as a versatile building block for esters, carbamates and other alkyl carbonate derivatives, and serves as a greener reagent in organic synthesis for specialty and fine chemical production.

4. For Industrial Solvent And Processing: As a high-purity aprotic solvent with a mild odor, DEC is used in extraction and polymer processing applications, offering formulators a safe, effective solvent option for industrial use.

5. Reliable Supply For Global Industry: Supplied in high-purity battery-grade and industrial-grade liquid with consistent quality, DEC gives battery, coatings and chemical manufacturers a dependable carbonate solvent with stable supply, flexible packaging and professional technical support.

 Quality Assurance 

Every batch of chemicals leaves our factory with complete laboratory documentation — not a promise, but verifiable test data. From incoming raw material inspection to finished-goods release, each batch is tested against published specifications, and a Certificate of Analysis (COA) accompanies every single shipment. What you order is exactly what we test — and what we ship.

Tested by our in-house ISO 9001:2015 laboratory. Verified independently by third-party labs on request (SGS / BV / Intertek). Traceable from raw material to your warehouse.
