Used as an intermediate in the synthesis of biologically active compounds, particularly in pharmaceutical research targeting central nervous system disorders. Its structure supports the development of novel therapeutics due to the presence of a trifluoromethylphenyl group, which enhances metabolic stability and lipophilicity. Commonly employed in the preparation of pyrrolidine-based drug candidates, especially those aiming at receptor modulation or enzyme inhibition. The tert-butyl carbamate (Boc) group allows for selective protection during multi-step organic synthesis, making it valuable in building complex molecules with high stereochemical control.
