Used as a chiral derivatizing agent in the synthesis of optically active compounds, particularly in the preparation of enantiomerically pure pharmaceuticals. Its asymmetric structure allows selective acylation in peptide and beta-lactam synthesis, making it valuable in developing antibiotics and other bioactive molecules. Also employed in resolving racemic mixtures due to its ability to form diastereomeric intermediates that can be easily separated. Commonly applied in research settings for stereocontrolled synthesis where high enantiomeric excess is required.
