Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
N-(1-(3,4-dichlorobenzyl)-2-oxo-1,2-dihydropyridin-3-yl)-2-nitrobenzamide (CAS 400086-18-2) is a high-purity analytical reference standard with the molecular formula C19H13Cl2N3O4 and a molecular weight of 418.23 g/mol.
N-(1-(3,4-dichlorobenzyl)-2-oxo-1,2-dihydropyridin-3-yl)-2-nitrobenzamide (C19H13Cl2N3O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, 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).
As a certified reference material (CRM), N-(1-(3,4-dichlorobenzyl)-2-oxo-1,2-dihydropyridin-3-yl)-2-nitrobenzamide 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.
