Used as a chiral catalyst ligand in asymmetric synthesis, particularly in enantioselective transformations such as hydrogenation and cross-coupling reactions. Its sterically hindered structure and electron-donating properties enhance selectivity and reactivity with transition metals like palladium, rhodium, and iridium. Commonly applied in pharmaceutical and fine chemical industries to produce single-enantiomer compounds. Exhibits high stability under various reaction conditions, making it suitable for industrial-scale processes requiring precise stereochemical control.
