Used as a chiral bidentate ligand in asymmetric catalysis, particularly in enantioselective transition metal-catalyzed reactions. Its sterically hindered, electron-rich phosphine groups and rigid chiral backbone make it effective in promoting high enantioselectivity in transformations such as hydrogenation, carbon-carbon bond formation, and cross-coupling reactions. Commonly employed in the synthesis of pharmaceuticals and fine chemicals where precise stereochemical control is required. The ligand’s stability under various reaction conditions enhances its utility in both academic and industrial research settings.
