Chemical Structure
Description
5-nitropyridine-2-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.
5-nitropyridine-2-sulfonyl fluoride (CAS 1935641-61-4) is a high-purity analytical reference standard with the molecular formula C5H3FN2O4S and a molecular weight of 206.15 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 5-nitropyridine-2-sulfonyl fluoride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
