Used as a chiral ligand in asymmetric catalysis, particularly in transition metal-catalyzed reactions such as hydrogenation and cross-coupling. Its rigid, sterically hindered structure enhances enantioselectivity, making it valuable in the synthesis of optically active pharmaceuticals and fine chemicals. Commonly employed in rhodium- and ruthenium-based catalytic systems to achieve high enantiomeric excess in the production of chiral amines and alcohols.
