Used as an intermediate in pharmaceutical synthesis, particularly in the development of bioactive molecules and drug candidates. Its structure incorporates a trifluoromethyl group, which can enhance metabolic stability and lipophilicity in target compounds. Commonly employed in the preparation of protease inhibitors and receptor modulators due to the conformational rigidity provided by the pyrrolidine ring. Also utilized in agrochemical research for designing novel active ingredients with improved efficacy and environmental stability.
