Used as a co-solvent in lithium-ion battery electrolytes due to its low viscosity, wide liquid temperature range, and compatibility with high-dielectric solvents, enabling effective dissolution of lithium salts in mixtures. It improves battery performance at low temperatures and contributes to the formation of a stable solid electrolyte interphase (SEI) layer on the anode. Also serves as a methylating and ethylating agent in organic synthesis, particularly in the production of pharmaceuticals and fine chemicals. Employed as a reactive solvent in transesterification reactions for the synthesis of polycarbonates and other carbonate esters. Its low toxicity and biodegradability make it suitable for use in environmentally friendly chemical processes.
