Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of protease inhibitors and other bioactive molecules. Its structure supports solid-phase peptide synthesis and is valuable in creating protected amino acid derivatives. Commonly employed in medicinal chemistry for constructing complex heterocyclic systems with potential antiviral or anticancer activity. Also utilized in research settings for developing novel enzyme inhibitors due to the reactivity of the oxadiazole and thiocarbonyl groups.
