Used as an ionic liquid in electrochemical applications such as batteries and supercapacitors due to its high ionic conductivity and thermal stability. It serves as a green solvent in organic synthesis, facilitating reactions like esterification and Heck coupling with easy product separation and recyclability. Employed in catalysis to stabilize metal nanoparticles, enhancing catalytic efficiency and reusability. Also applied in separation processes, including CO₂ capture and extraction of biomolecules, thanks to its tunable solubility and low volatility.
