Description

Ethylene Carbonate (CAS 96-49-1) is a high-purity cyclic carbonate ester with the molecular formula C₃H₄O₃, widely utilized in advanced electrochemical and industrial applications. This colorless, crystalline solid (or liquid above 36??C) is characterized by its exceptional polarity, high dielectric constant (??_r ?? 89), and broad electrochemical stability window, making it a critical component in lithium-ion battery electrolytes. Its IUPAC name, 1,3-dioxolan-2-one, reflects its cyclic carbonate structure, which enhances ionic conductivity when blended with solvents like dimethyl carbonate (DMC). Ethylene Carbonate is rigorously tested for trace metals (<1 ppm) and water content (<50 ppm) to meet research-grade and industrial standards. Available in 99.9% purity, it is packaged under inert gas to ensure stability and shipped with detailed technical documentation, including MSDS, COA, and NMR spectra.

Application

Ethylene Carbonate serves as a key solvent in lithium-ion battery electrolytes, where it facilitates lithium salt dissociation and stabilizes SEI layers on anodes. It is also employed as a polar aprotic solvent in organic synthesis, particularly in carboxylation and transesterification reactions. Industrial applications include use as a plasticizer for polymers and a precursor for polycarbonate resins.
