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 indole core with electron-withdrawing trifluoromethyl group enhances binding affinity and metabolic stability in drug candidates. Commonly employed in medicinal chemistry for structure-activity relationship studies due to its ability to mimic natural indole derivatives while offering improved pharmacokinetic properties. Also utilized in the preparation of bioactive molecules for research in neuropharmacology and oncology.
