Used as a bidentate phosphine ligand in homogeneous catalysis, particularly in transition metal-catalyzed reactions such as hydrogenation, hydroformylation, and cross-coupling reactions. Its unique electronic and steric properties enhance catalyst stability and selectivity. Commonly coordinates with metals like palladium, rhodium, and ruthenium to form active catalytic species. Valued in asymmetric synthesis when paired with chiral centers, enabling enantioselective transformations in pharmaceutical and fine chemical manufacturing.
