Chemical Structure
Description
As a certified reference material (CRM), 5-Fluoro-n-methylpyridine-3-sulfonamide 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.
5-Fluoro-n-methylpyridine-3-sulfonamide (CAS 1249592-68-4) is a high-purity analytical reference standard with the molecular formula C6H7FN2O2S and a molecular weight of 190.20 g/mol.
5-Fluoro-n-methylpyridine-3-sulfonamide (C6H7FN2O2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
