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.
