Used as a building block in pharmaceutical synthesis, particularly in the development of agrochemicals and medicinal compounds where trifluoromethyl groups enhance metabolic stability and lipophilicity. Commonly employed in the preparation of kinase inhibitors and other biologically active molecules. Also utilized in the synthesis of specialty materials and ligands for catalysis due to the electron-withdrawing nature of the trifluoromethyl group, which influences reactivity and binding properties.
