Used as a chiral ligand in asymmetric catalysis, particularly in enantioselective hydrogenation and transfer hydrogenation reactions. Its rigid, C2-symmetric structure enhances stereocontrol, making it valuable in the synthesis of chiral amines and pharmaceutical intermediates. Commonly employed in ruthenium- or rhodium-catalyzed systems for high enantioselectivity. Also applied in the development of catalysts for fine chemicals and active pharmaceutical ingredients (APIs) where precise stereochemistry is critical.
