Used as a chiral derivatizing agent in asymmetric synthesis, particularly in the preparation of enantiomerically pure phosphorus-containing compounds. Its unique stereochemistry and electron-withdrawing perfluorophenylthio group make it effective in catalyzing enantioselective transformations, especially in organocatalysis and coordination chemistry with transition metals. Commonly employed in the development of chiral ligands for asymmetric hydrogenation and cross-coupling reactions. Also finds use in analytical chemistry for the resolution of racemic mixtures through diastereomeric adduct formation.
