Used as an ionic liquid in catalysis and organic synthesis due to its high thermal stability and low volatility. Commonly employed as a green solvent in reactions such as Heck coupling, Diels-Alder, and hydrogenation, where it enhances reaction rates and selectivity. Its non-aqueous nature and good solvation properties make it suitable for electrochemical applications, including batteries and capacitors. Also utilized in separation processes, such as extraction of metals or removal of sulfur compounds from fuels. Stable under a wide range of conditions, it supports recyclable reaction systems, reducing waste in industrial processes.
