Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of serotonin receptor modulators and other central nervous system agents. Its structure supports the creation of bioactive molecules due to the electron-withdrawing trifluoromethyl group enhancing metabolic stability and binding affinity. Commonly employed in medicinal chemistry for constructing indole-based drug candidates with improved pharmacokinetic properties. Also utilized in agrochemical research for designing novel pesticides and herbicides owing to its reactivity and structural features.
