Used as a chiral resolving agent in the pharmaceutical industry for the separation of enantiomers, particularly in the production of optically active drugs. Its stereochemical purity allows efficient resolution of racemic mixtures through diastereomeric salt formation. Commonly applied in the synthesis of angiotensin-converting enzyme (ACE) inhibitors and other bioactive molecules where enantiomeric purity is critical. Also utilized in asymmetric synthesis as a chiral auxiliary to control stereochemistry in complex organic transformations.
