Used as a chiral resolving agent in organic synthesis, particularly for the separation of enantiomers of basic compounds such as amines. Its structural specificity allows it to form diastereomeric salts with racemic mixtures, enabling the isolation of optically active components through crystallization. Also employed in asymmetric synthesis and as a chiral auxiliary in the development of pharmaceutical intermediates. Shows utility in chromatographic separations when used as a chiral selector.
