Chemical Structure

5-Fluoro-2-methyl-4-nitropyridine 1-Oxide CAS 113209-88-4 chemical structure

Description

Based on its molecular formula C6H5FN2O3, 5-Fluoro-2-methyl-4-nitropyridine 1-Oxide contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 172.11 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
