Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of compounds with biological activity. Its structure supports the creation of thiourea derivatives that can act as enzyme inhibitors or receptor ligands. Commonly employed in medicinal chemistry for optimizing lead compounds due to the electron-withdrawing properties of the trifluoromethylthio group, which can enhance metabolic stability and membrane permeability. Also utilized in the design of novel pesticides and herbicides, where the moiety contributes to improved efficacy and selectivity.
