Used as a chiral ligand in asymmetric synthesis, particularly in catalytic reactions where high enantioselectivity is required. Its rigid, bidentate structure makes it effective in coordinating with transition metals such as palladium, rhodium, and ruthenium, enabling efficient stereocontrol in hydrogenation, coupling, and cyclization reactions. Commonly applied in pharmaceutical research for the development of enantiomerically pure compounds. Also utilized in the design of catalysts for fine chemical production due to its stability under various reaction conditions.
