Used as a chiral ligand in asymmetric catalysis, particularly in transition-metal-catalyzed reactions. It plays a key role in enantioselective hydrogenation and cross-coupling reactions, where high stereocontrol is required. Its structure allows for strong coordination to metals like rhodium or ruthenium, enhancing catalytic activity and selectivity. Commonly employed in the synthesis of pharmaceutical intermediates and fine chemicals where specific enantiomer formation is critical.
