Used as a polar aprotic solvent in organic synthesis, particularly in reactions involving organometallic compounds due to its ability to stabilize anions and solubilize salts. Commonly employed in battery electrolytes for lithium-ion and lithium-metal batteries, enhancing ion conductivity and improving electrode stability. Also utilized in pharmaceutical formulations as a solubilizing agent and in polymer science as a compatibilizer or plasticizer. Its low volatility and high thermal stability make it suitable for use in high-temperature reactions and extraction processes.
