Used as a chiral catalyst ligand in asymmetric synthesis, particularly in enantioselective transformations such as hydrogenation and C–C bond-forming reactions. Its sterically hindered, electron-deficient structure enhances selectivity and reactivity with transition metals like rhodium or iridium, making it valuable in pharmaceutical and fine chemical manufacturing where high enantiomeric purity is required. The compound’s stability under oxidative conditions also supports its use in catalytic cycles involving redox-active metal centers.
