Description
CATO manufactures 4-Bromo-2-fluoro-N-methylbenzenesulfonamide 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.
4-Bromo-2-fluoro-N-methylbenzenesulfonamide (CAS 749928-85-6), molecular formula C7H7BrFNO2S and molecular weight 268.10 g/mol, is a CATO reference standard with documented purity and traceability.
4-Bromo-2-fluoro-N-methylbenzenesulfonamide (C7H7BrFNO2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. 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.
