Used in pharmaceutical synthesis as a building block for bioactive molecules, particularly in the development of drugs targeting central nervous system disorders. Its trifluoromethyl group enhances metabolic stability and lipophilicity, improving blood-brain barrier penetration. Commonly employed in the preparation of selective enzyme inhibitors and receptor ligands. Also utilized in agrochemical research for designing novel pesticides with improved efficacy and environmental stability. The hydroiodide salt form increases crystallinity and handling stability during manufacturing processes.
