Description
As a certified reference material (CRM), n-(4-Bromo-2,6-dichlorophenyl)methanesulfonamide 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.
n-(4-Bromo-2,6-dichlorophenyl)methanesulfonamide (CAS 1339325-56-2) is a high-purity analytical reference standard with the molecular formula C7H6BrCl2NO2S and a molecular weight of 319.00 g/mol.
Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system, n-(4-Bromo-2,6-dichlorophenyl)methanesulfonamide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 319.00 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
