Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of central nervous system (CNS) active agents. It serves as a building block for drugs targeting neurological disorders, including antidepressants and antipsychotics. Its trifluoromethylphenyl group enhances metabolic stability and lipophilicity, improving blood-brain barrier penetration. Also employed in the preparation of selective enzyme inhibitors and receptor modulators due to its structural rigidity and electronic properties. Commonly utilized in research settings for structure-activity relationship (SAR) studies in medicinal chemistry.
