Used as an ionic liquid in organic synthesis and catalysis due to its high thermal stability and low volatility. Commonly serves as a solvent or catalyst support in cross-coupling reactions, such as Heck and Suzuki reactions, enhancing reaction efficiency and selectivity. Also employed in electrochemical applications, including as an electrolyte component in batteries and capacitors, where its wide electrochemical window and ionic conductivity are advantageous. Its non-volatile nature makes it suitable for green chemistry processes aiming to reduce hazardous solvent use.
