Used as a polar aprotic solvent in organic synthesis, particularly in pharmaceutical and fine chemical manufacturing. It facilitates reactions such as nucleophilic substitutions and couplings due to its high solvating power and thermal stability. Also employed in electrochemical applications, including battery electrolytes, where it helps improve ion conductivity and electrode performance. Its low volatility and good dielectric properties make it suitable for use in specialty formulations and as a reaction medium in high-temperature processes.
