Used as a chiral ligand in asymmetric synthesis, particularly in catalytic enantioselective reactions. Its rigid structure and well-defined stereochemistry make it effective in inducing high enantioselectivity in transformations such as hydrogenation and transfer hydrogenation of prochiral ketones and imines. Commonly employed in conjunction with transition metals like ruthenium or rhodium to form catalytically active complexes. Also applied in the development of chiral catalysts for pharmaceutical synthesis where control of stereochemistry is critical. Its dihydrochloride salt form enhances solubility and stability, facilitating handling and storage in industrial and laboratory settings.
