Used as a solvent in lithium-ion battery electrolytes due to its high dielectric constant and low viscosity, enhancing ion conductivity. It improves battery performance at low temperatures and contributes to the formation of a stable solid electrolyte interphase (SEI) on the anode. Also serves as an intermediate in organic synthesis and as a methylating agent in some chemical reactions. Its low boiling point makes it useful in processes requiring easy removal by distillation.
