Used as an ionic liquid in organic synthesis and catalysis due to its excellent solvent properties and thermal stability. Commonly employed in reactions such as Heck and Suzuki couplings where it enhances reaction rates and catalyst recyclability. Its non-volatile nature makes it suitable for high-temperature processes, reducing the need for volatile organic solvents. Also investigated in electrochemical applications, including as an electrolyte component in batteries and fuel cells, owing to its good ionic conductivity and wide electrochemical window. Additionally, utilized in separation processes and as a medium for CO₂ capture due to its tunable polarity and solvation characteristics.
