Used as a chiral ligand in asymmetric catalysis, particularly in transition metal-catalyzed reactions such as hydrogenation and cross-coupling. Its rigid, stereodefined structure enhances enantioselectivity, making it valuable in the synthesis of optically active pharmaceuticals and fine chemicals. The phosphorus centers coordinate effectively with metals like rhodium, ruthenium, and palladium, enabling high catalytic efficiency and stereocontrol. Commonly employed in research and industrial settings for the development of enantiopure compounds.
