Description

Ethyl Methyl Carbonate (CAS No. 623-53-0) is a high-purity carbonate ester solvent with the molecular formula C₄H₈O₃. This colorless, low-viscosity liquid is widely used as a non-aqueous electrolyte solvent in lithium-ion batteries due to its excellent electrochemical stability, high dielectric constant, and broad liquid temperature range. As a co-solvent, it enhances ionic conductivity while maintaining thermal and chemical stability in battery formulations. Our Ethyl Methyl Carbonate is synthesized under strict quality control, ensuring >99.5% purity with minimal water content (<50 ppm) and low acidity. Suitable for both research and industrial applications, it is supplied in sealed, nitrogen-purged containers to prevent moisture absorption and degradation. Ideal for advanced battery research, organic synthesis, and specialty solvent applications requiring a polar aprotic solvent with good solvating power.

Application

Ethyl Methyl Carbonate serves as a key component in lithium-ion battery electrolytes, where it improves low-temperature performance and cycle life. It functions as a co-solvent in combination with ethylene carbonate and linear carbonates for high-voltage battery systems. The compound is also used as a solvent for organic synthesis and as a precursor for transesterification reactions. In material science, it finds application as a processing solvent for polymers and resins.
