Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 4-Bromo-2,3-dichlorobenzenesulfonamide (CAS 1208075-94-8), a certified reference material (molecular formula C6H4BrCl2NO2S, MW 304.98 g/mol) for analytical method development and quality control.
4-Bromo-2,3-dichlorobenzenesulfonamide (C6H4BrCl2NO2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), 4-Bromo-2,3-dichlorobenzenesulfonamide 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.
