Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of central nervous system (CNS) active compounds. It serves as a building block for serotonin receptor modulators and is involved in the preparation of antidepressants and antipsychotic drugs. Its trifluoromethyl-substituted aromatic structure enhances metabolic stability and lipophilicity, making it valuable in medicinal chemistry for improving drug bioavailability and target binding affinity. Also utilized in research settings to design novel bioactive molecules and in the discovery of selective receptor ligands.
