Used as a chiral ligand in asymmetric catalysis, particularly in transition metal-catalyzed reactions such as hydrogenation and cross-coupling. Its structure enables high enantioselectivity, making it valuable in the synthesis of optically active pharmaceuticals and fine chemicals. Commonly coordinates with rhodium, ruthenium, or palladium to form catalysts that efficiently produce single-enantiomer products. Widely applied in academic and industrial research for developing stereoselective synthetic routes.
