Chemical Structure
Description
As a certified reference material (CRM), 1-(2,6-Dichlorophenyl)-n-methylmethanesulfonamide 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.
1-(2,6-Dichlorophenyl)-n-methylmethanesulfonamide (CAS 928928-75-0), molecular formula C8H9Cl2NO2S and molecular weight 254.13 g/mol, is a CATO reference standard with documented purity and traceability.
1-(2,6-Dichlorophenyl)-n-methylmethanesulfonamide (C8H9Cl2NO2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
