Widely used as a chiral ligand in asymmetric catalysis, this compound plays a key role in enantioselective hydrogenation reactions. It is particularly effective in the synthesis of chiral amines and amino acids, which are important intermediates in pharmaceutical manufacturing. Due to its ability to coordinate with transition metals like rhodium and ruthenium, it enhances stereoselectivity and catalytic efficiency in homogeneous catalytic systems. Its application extends to the production of fine chemicals and active pharmaceutical ingredients where high optical purity is required.
