Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of bioactive molecules and agrochemicals. Its strong electron-withdrawing trifluoromethyl groups enhance metabolic stability and binding affinity in drug candidates. Commonly employed in the preparation of thiourea derivatives and heterocyclic compounds with potential antimicrobial, antifungal, or anti-inflammatory properties. Also utilized in medicinal chemistry research for structure-activity relationship (SAR) studies due to its rigid aromatic scaffold and hydrogen-bonding capability.
