(S,S)-BenzP is primarily used as a chiral ligand in asymmetric catalysis, particularly in transition metal-catalyzed reactions. It is highly effective in enantioselective hydrogenation, where it helps produce chiral molecules with high selectivity. This makes it valuable in the synthesis of pharmaceuticals, agrochemicals, and fine chemicals, where precise stereochemistry is crucial. Its robust structure and ability to form stable complexes with metals like rhodium and iridium enhance its utility in creating complex organic compounds with high enantiomeric purity.
