Used as a chiral ligand in asymmetric catalysis, particularly in transition metal-catalyzed reactions such as 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 manufacturing. Effective with rhodium, ruthenium, and palladium complexes, it helps produce enantiomerically pure intermediates. Soluble in common organic solvents, it supports homogeneous reaction conditions for consistent catalytic performance.
