Chemical Structure
Description
CATO supplies 2-Bromo-5-chloro-n-ethyl-4-methylbenzenesulfonamide (CAS 1246823-46-0), a certified reference material (molecular formula C9H11BrClNO2S, MW 312.61 g/mol) for analytical method development and quality control.
2-Bromo-5-chloro-n-ethyl-4-methylbenzenesulfonamide (C9H11BrClNO2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. 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.
As a certified reference material (CRM), 2-Bromo-5-chloro-n-ethyl-4-methylbenzenesulfonamide 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.
