Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antiviral and anticancer agents. Its structure supports the design of bioactive molecules due to the electron-withdrawing trifluoromethyl group enhancing metabolic stability and membrane permeability. Commonly employed in medicinal chemistry for constructing heterocyclic compounds with improved pharmacokinetic properties. Also utilized in agrochemical research for developing new active ingredients with enhanced activity and selectivity.
