Used as a chiral diamine ligand and advanced organic synthesis intermediate. It is widely applied in asymmetric catalysis, transition-metal catalytic reactions, chiral pharmaceutical synthesis, and preparation of functional organic materials. The binaphthyl framework provides axial chirality and makes it an important building block for chiral catalysts and optoelectronic molecules.
