Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of bioactive molecules targeting central nervous system disorders. Its structure supports the construction of conformationally constrained analogs, enhancing metabolic stability and receptor selectivity. Commonly employed in medicinal chemistry for optimizing drug candidates due to the presence of fluorinated groups, which improve lipophilicity and membrane permeability. Also utilized in the preparation of protease inhibitors and other therapeutic agents where nitrogen-containing heterocycles are required.
