Used in pharmaceutical research as a key intermediate in the synthesis of biologically active compounds, particularly in the development of central nervous system agents. It serves as a building block for novel drug candidates due to its structural similarity to known neuroactive molecules. Its trifluoromethylphenyl group enhances metabolic stability and lipophilicity, making it valuable in optimizing drug potency and pharmacokinetics. Also employed in the study of receptor binding, especially for dopamine and serotonin receptors, aiding in the design of antidepressants and antipsychotics.
