Used as an intermediate in pharmaceutical synthesis, particularly in the development of kinase inhibitors and other bioactive molecules. Its structure supports conjugation in peptide-based drugs and facilitates improved metabolic stability due to the trifluoroethyl group. Commonly employed in research settings for designing proteolysis-targeting chimeras (PROTACs) and targeted protein degraders, where it acts as a linker or warhead component. Also utilized in agrochemical research for designing novel active ingredients with enhanced lipophilicity and membrane permeability.
