Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antidiabetic and antiviral drugs. Its structure supports the design of enzyme inhibitors due to the presence of both sulfur and nitrogen heteroatoms, which enhance binding to active sites in target proteins. Commonly employed in medicinal chemistry for scaffold modification to improve drug potency and metabolic stability. Also utilized in the preparation of peptidomimetics and bioactive molecules where conformational restraint is required.
