Used as a chiral ligand in asymmetric catalysis, particularly in transition metal-catalyzed reactions such as asymmetric hydrogenation and carbon-carbon bond formation. Its rigid biphenyl backbone and well-positioned amino groups allow for strong coordination to metals like rhodium, ruthenium, and palladium, enabling high enantioselectivity in the synthesis of pharmaceutical intermediates and fine chemicals. Commonly employed in the production of optically active amines and amino acids. Also utilized in the development of chiral sensors and asymmetric synthesis routes in academic and industrial research settings.
