Used as a chiral ligand in asymmetric catalysis, particularly in enantioselective transformations such as alkylations, aldol reactions, and Diels-Alder reactions. Its rigid, bidentate structure enhances stereocontrol when coordinated to metal centers like copper or zinc, making it valuable in the synthesis of optically active pharmaceuticals and fine chemicals. Commonly employed in academic and industrial research for developing stereoselective synthetic routes.
