Used as a chiral ligand in asymmetric catalysis, particularly in enantioselective hydrogenation and transfer hydrogenation reactions. Its rigid, sterically hindered structure enhances stereoselectivity, making it valuable in the synthesis of chiral amines and alcohols for pharmaceuticals. Also employed in coordination chemistry to form complexes with transition metals like ruthenium and rhodium, improving catalytic efficiency and enantiocontrol. Suitable for fine chemical synthesis where high optical purity is required.
