Used as an intermediate in the synthesis of pharmaceuticals, particularly in the production of beta-lactam antibiotics and other bioactive compounds. It plays a role in peptide coupling reactions, where the tert-butoxycarbonyl (Boc) group acts as a protective group for amines during chemical synthesis. The compound is also utilized in the development of chiral molecules due to its hydroxyl and carboxyl functional groups, which are essential for stereoselective transformations. Additionally, it finds application in the preparation of prodrugs and other drug delivery systems, enhancing the stability and bioavailability of active pharmaceutical ingredients.
