Used as a precursor in the synthesis of N-heterocyclic carbene (NHC) ligands, which play a key role in organometallic catalysis. These catalysts are widely applied in cross-coupling reactions, olefin metathesis, and polymerization processes. The compound’s stable imidazolium core allows for easy modification and enhanced catalytic performance in both academic and industrial research settings. It is also explored in the development of ionic liquids for green chemistry applications due to its thermal stability and low volatility.
