Used primarily as a chiral derivatizing agent in organic synthesis, especially for the resolution of racemic mixtures of alcohols and amines. Its ability to form diastereomeric esters or amides allows for separation by conventional techniques such as crystallization or chromatography. Commonly employed in the preparation of chiral auxiliaries and in asymmetric synthesis where stereochemical control is critical. Also utilized in the pharmaceutical industry for the purification and analysis of enantiomerically pure compounds.
