Used as an intermediate in the synthesis of biologically active compounds, particularly in pharmaceutical research. Its structure supports the development of molecules with central nervous system activity. The presence of fluorine atoms enhances metabolic stability and membrane permeability, making it valuable in optimizing drug candidates. Commonly employed in the preparation of novel receptor modulators and enzyme inhibitors. Also utilized in medicinal chemistry for structure-activity relationship (SAR) studies due to its conformational rigidity and ability to mimic peptide bonds.
