Used as a chiral ligand in asymmetric catalysis, particularly in transition-metal-catalyzed reactions such as asymmetric hydrogenation and cross-coupling. Its rigid, bidentate structure enables high enantioselectivity in the synthesis of chiral molecules, making it valuable in pharmaceutical and fine chemical industries for producing single-enantiomer compounds. Commonly employed in palladium- and rhodium-based catalytic systems, it helps achieve high catalytic efficiency and stereochemical control under mild reaction conditions.
