6-Cyano-5-(difluoromethyl)-2-iodopyridine-3-sulfonamide (CAS 1805285-09-9), molecular formula C7H4F2IN3O2S and molecular weight 359.09 g/mol, is a CATO reference standard with documented purity and traceability.
6-Cyano-5-(difluoromethyl)-2-iodopyridine-3-sulfonamide (C7H4F2IN3O2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/iodine 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.
