Used as an ionic liquid in organic synthesis and catalysis due to its ability to stabilize reactive intermediates and enhance reaction rates. Commonly employed as a solvent or catalyst support in cross-coupling reactions, including Heck and Suzuki reactions. Its low volatility and high thermal stability make it suitable for green chemistry applications. Also investigated in electrochemistry for use in batteries and capacitors due to good ionic conductivity. Additionally, serves as a processing agent in biomass dissolution and cellulose derivatization, enabling sustainable material production.
