Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3-{5,6-dichloro-1-[(3-chlorophenyl)methyl]-1H-1,3-benzodiazol-2-yl}-1,2-dihydropyridin-2-one (CAS 338774-22-4) is a high-purity analytical reference standard with the molecular formula C19H12Cl3N3O and a molecular weight of 404.68 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 3-{5,6-dichloro-1-[(3-chlorophenyl)methyl]-1H-1,3-benzodiazol-2-yl}-1,2-dihydropyridin-2-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 404.68 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 3-{5,6-dichloro-1-[(3-chlorophenyl)methyl]-1H-1,3-benzodiazol-2-yl}-1,2-dihydropyridin-2-one 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.
