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 2-[N-(2,4-Dichloro-5-methoxyphenyl)methanesulfonamido]-N-methyl-N-phenylacetamide (CAS 672951-75-6), a certified reference material (molecular formula C17H18Cl2N2O4S, MW 417.31 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, 2-[N-(2,4-Dichloro-5-methoxyphenyl)methanesulfonamido]-N-methyl-N-phenylacetamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 417.31 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
CATO manufactures 2-[N-(2,4-Dichloro-5-methoxyphenyl)methanesulfonamido]-N-methyl-N-phenylacetamide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
