Description

Dimethyl carbonate (CAS 616-38-6) is a high-purity, versatile organic carbonate ester with the molecular formula C₃H₆O₃. This colorless, flammable liquid exhibits a mild, pleasant odor and is widely utilized as a green solvent, methylating agent, and electrolyte component in lithium-ion batteries. With a boiling point of 90°C and a flash point of 17°C, it offers excellent solvency for resins, oils, and polymers while maintaining low toxicity and biodegradability. Our pharmaceutical-grade dimethyl carbonate (≥99.9% purity) is rigorously tested for residual solvents, heavy metals, and water content, ensuring optimal performance in synthetic chemistry, battery research, and industrial applications. Packaged under inert gas in amber glass bottles or specialized corrosion-resistant containers to prevent moisture absorption and degradation.
