Used as an ionic liquid in organic synthesis and catalysis, particularly in reactions requiring high thermal stability and low volatility. It serves as a solvent or catalyst support in cross-coupling reactions and CO2 capture processes due to its tunable polarity and strong solvation properties. Also applied in electrochemistry for electrolyte formulations where high ionic conductivity and wide electrochemical windows are required. Its bulky alkyl groups enhance steric stabilization of reactive intermediates, making it useful in transition metal-catalyzed transformations.
