Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of protease inhibitors and other bioactive molecules. Its structure allows for selective modification in peptide-based drug design, enhancing metabolic stability and binding affinity. Commonly employed in medicinal chemistry for introducing trifluoromethyl thioether moieties, which can improve lipophilicity and bioavailability. Also utilized in agrochemical research for designing novel active ingredients with improved resistance profiles.
