Chemical Structure
Description
2-nitropyridine-3-sulfonyl fluoride (C5H3FN2O4S) contains a carbohydrate-derived structure, an amide group, a sulfone group, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
2-nitropyridine-3-sulfonyl fluoride (CAS 1989671-97-7) is a high-purity analytical reference standard with the molecular formula C5H3FN2O4S and a molecular weight of 206.15 g/mol.
