Used primarily as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of fluorinated active pharmaceutical ingredients (APIs). Its structure allows for selective functionalization, making it valuable in constructing complex molecules with enhanced metabolic stability and bioavailability. Commonly employed in peptide modifications and in the preparation of protease inhibitors. Also utilized in research settings for labeling and tracer studies due to the presence of fluorine, which facilitates detection by 19F NMR spectroscopy.
