FNPA [4-Fluoro-3-nitrophenyl azide] is a highly reactive photoaffinity labeling reagent used in the study of protein interactions and molecular recognition processes. The azide group enables the formation of a covalent bond with target molecules upon UV irradiation, while the nitrophenyl moiety provides stability and specificity. FNPA is particularly useful in identifying binding sites, mapping protein-ligand interactions, and exploring enzyme mechanisms. Its versatility and efficiency make it a valuable tool in advanced biochemical and pharmaceutical research.
