Used in research to study protein structure and function by incorporating non-natural amino acids into peptides and proteins. It serves as a precursor in the synthesis of fluorinated analogs of biologically active compounds, enabling exploration of metabolic pathways and enzyme mechanisms. Commonly applied in medicinal chemistry for developing potential pharmaceuticals, especially in oncology and neurology, where fluorine substitution can enhance drug stability, bioavailability, and target binding. Also utilized in NMR studies due to the fluorine atom acting as a sensitive spectroscopic probe.
