Used as an ionic liquid in electrochemical applications such as batteries and capacitors due to its high thermal stability and low volatility. Acts as a green solvent in organic synthesis, including alkylation and acylation reactions, facilitating high yields, easy separation, and recyclability. Employed in separation processes, including CO₂ capture and metal extraction, thanks to its tunable solubility and selectivity. Also functions as a surfactant in nanomaterial synthesis, controlling the shape and size of nanoparticles (e.g., silver or gold) for improved dispersion and green chemistry processes. Explored in lubrication systems where conventional fluids may degrade under extreme conditions.
