Description
As a certified reference material (CRM), 2-Bromo-6-chloro-4-fluorobenzenesulfonamide 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.
CATO supplies 2-Bromo-6-chloro-4-fluorobenzenesulfonamide (CAS 1208075-45-9), a certified reference material (molecular formula C6H4BrClFNO2S, MW 288.52 g/mol) for analytical method development and quality control.
2-Bromo-6-chloro-4-fluorobenzenesulfonamide (C6H4BrClFNO2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/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. 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.
