Used in the synthesis of pharmaceutical intermediates, particularly in the development of chiral compounds for drug manufacturing. Its thiol groups enable conjugation reactions, making it valuable in creating targeted therapeutics and prodrugs. Also employed in asymmetric synthesis due to its chiral amine functionality, supporting the production of enantiomerically pure substances. Additionally, serves as a building block in peptide mimetics and in the design of enzyme inhibitors where sulfur-containing groups are required for activity.
