Used as a high-polarity solvent in lithium-ion battery electrolytes due to its excellent solvating ability for lithium salts. It helps form a stable solid electrolyte interphase (SEI) on the anode, improving battery cycle life and safety. Also serves as an intermediate in chemical synthesis, particularly in the production of ethylene glycol and polycarbonates. Its high boiling point and biodegradability make it suitable for use in specialty cleaning formulations and as a solvent in gas treating processes to remove CO₂ and H₂S. Additionally, employed in some cosmetic and pharmaceutical formulations as a solubilizing agent.
