Used as a chiral ligand in asymmetric catalysis, particularly in enantioselective synthesis of pharmaceuticals and fine chemicals. Its rigid structure and well-defined stereochemistry make it effective in promoting high enantioselectivity in reactions such as hydrogenation, epoxidation, and C–C bond formation. Commonly employed in transition metal complexes with rhodium, ruthenium, or iridium for catalytic transformations requiring precise stereochemical control. Also utilized in the development of chiral sensors and separation materials due to its ability to differentiate enantiomers.
