Used as a chiral derivatizing agent in the resolution of racemic mixtures, particularly in the separation of enantiomers of carboxylic acids and amines. Its chiral center allows for the formation of diastereomeric derivatives that can be separated by conventional chromatography or crystallization. Commonly employed in asymmetric synthesis and pharmaceutical research where enantiomeric purity is critical. Also utilized as an intermediate in the preparation of chiral ligands and catalysts for enantioselective reactions.
