Used as a chiral resolving agent in the separation of enantiomers, particularly in the pharmaceutical industry. Its asymmetric structure allows it to form diastereomeric salts with racemic mixtures of basic compounds, enabling the isolation of optically pure enantiomers through crystallization. Commonly applied in the resolution of amines and amino acid derivatives. Also employed in asymmetric synthesis as a chiral auxiliary or intermediate due to its stereochemical stability and derivatization potential.
