Used as a chiral derivatizing agent in stereochemical analysis, particularly in the determination of enantiomeric purity of amines and amino acids. Its structure allows selective binding to target molecules, enhancing resolution in chromatographic and electrophoretic techniques. Also employed in asymmetric synthesis as a ligand or auxiliary due to its rigid, stereodefined framework with sulfur-containing linkages that support metal coordination. Shows utility in pharmaceutical research for developing enantioselective catalysts and probing biological interactions involving chiral environments.
