Used as a chiral ligand in asymmetric catalysis, particularly in enantioselective synthesis of pharmaceuticals and fine chemicals. Its steric bulk and defined stereochemistry enable high enantioselectivity in transition metal-catalyzed reactions such as hydrogenation and cross-coupling. Commonly employed with rhodium or ruthenium complexes to control stereochemical outcomes in the formation of chiral centers. Valued for its stability and reusability in catalytic cycles, making it suitable for industrial-scale asymmetric transformations.
