Used as a ligand in organometallic chemistry, particularly in the formation of N-heterocyclic carbene (NHC) complexes. These complexes are valuable catalysts in various organic transformations, including cross-coupling reactions, olefin metathesis, and hydrogenation processes. Due to its extended aromatic system and electron-donating properties, it enhances the stability and activity of metal catalysts. It is also explored in materials science for designing metal-organic frameworks (MOFs) and in medicinal chemistry as a scaffold for bioactive molecules.
