Used as a polar aprotic solvent in lithium-ion battery electrolytes due to its high dielectric constant and good solvating ability. It helps improve electrolyte stability and enhances battery performance at low temperatures. Also serves as an intermediate in organic synthesis, particularly in the production of polycarbonates and other carbonate esters. Its biodegradability and low toxicity make it suitable for use in environmentally friendly chemical processes. Additionally, it finds application as a coupling agent in some polymer systems and as a component in specialty cleaning formulations.
