Used as an ionic liquid in electrochemical applications such as batteries, fuel cells, supercapacitors, chemical sensors, and electronics due to its high ionic conductivity, wide electrochemical stability window, and thermal stability with low volatility. It serves as a solvent for organic reactions and catalysis, especially where precise control of temperature and pressure is required. Commonly employed in separation processes, including extraction of metals and desulfurization of fuels. Also utilized in green chemistry initiatives as a reusable, non-volatile medium that reduces environmental impact.
