Used as an ionic liquid in catalytic reactions and organic synthesis due to its high thermal stability and low volatility. Commonly employed as a solvent or catalyst support in cross-coupling reactions, such as Heck and Suzuki reactions, where it enhances reaction efficiency and recyclability of catalysts. Its non-aqueous polar nature makes it suitable for electrochemical applications, including use in batteries and capacitors. Also applied in separation processes, such as extraction of organic compounds or metal ions, thanks to its selective solvation properties.
