Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of bioactive molecules targeting central nervous system disorders and inflammatory diseases. Its structural features, including the trifluoromethylphenyl group and the Boc-protected pyrrolidine, make it valuable in medicinal chemistry for constructing peptidomimetics and enzyme inhibitors. Commonly employed in research settings for structure-activity relationship (SAR) studies due to its stereochemical stability and ability to modulate lipophilicity and metabolic resistance in drug candidates.
