Used as an ionic liquid in catalytic reactions, particularly in palladium-catalyzed cross-coupling reactions such as Suzuki and Heck reactions. Enhances catalyst stability and reaction efficiency by providing a polar, non-coordinating environment. Also serves as a precursor for N-heterocyclic carbene ligands in organometallic chemistry. Its bulky isopropyl groups contribute to steric stabilization of reactive intermediates. Applied in electrochemical systems due to good ionic conductivity and thermal stability.
