Used as a chiral ligand in asymmetric catalysis, particularly in enantioselective hydrogenation reactions. Its sterically hindered structure and electron-withdrawing trifluoromethyl groups enhance selectivity and stability in transition metal complexes. Commonly employed with rhodium or ruthenium catalysts to produce high enantiomeric excess in pharmaceutical intermediates and fine chemicals. Valued for its role in synthesizing optically active compounds in academic and industrial research settings.
