Used in pharmaceutical research as an intermediate in the synthesis of biologically active compounds, particularly in the development of central nervous system agents. Shows potential in the study of neurological disorders due to its structural properties that support blood-brain barrier penetration. Also employed in medicinal chemistry for structure-activity relationship (SAR) studies involving pyrrolidine-based scaffolds. Its trifluoromethylphenyl group enhances metabolic stability and lipophilicity, making it valuable in optimizing drug candidates for improved pharmacokinetics.
