Description
CATO manufactures 6-Amino-4-(difluoromethyl)-5-nitropyridine-3-sulfonamide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
CATO supplies 6-Amino-4-(difluoromethyl)-5-nitropyridine-3-sulfonamide (CAS 1805228-25-4), a certified reference material (molecular formula C6H6F2N4O4S, MW 268.20 g/mol) for analytical method development and quality control.
6-Amino-4-(difluoromethyl)-5-nitropyridine-3-sulfonamide (C6H6F2N4O4S) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
