Used as a chiral ligand in asymmetric catalysis, particularly in transition metal-catalyzed reactions. It plays a key role in enantioselective transformations such as hydrogenation, coupling reactions, and conjugate additions, where high stereochemical control is required. Its structure allows for strong coordination to metals like rhodium, ruthenium, and palladium, enhancing catalytic activity and enantioselectivity. Commonly applied in pharmaceutical synthesis and fine chemical production to generate single-enantiomer compounds.
