Chemical Structure
Description
N-benzyl-1-(3-chlorobenzyl)-2-oxo-1,2-dihydropyridine-3-carboxamide (CAS 339008-71-8) is a high-purity analytical reference standard with the molecular formula C20H17ClN2O2 and a molecular weight of 352.81 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, N-benzyl-1-(3-chlorobenzyl)-2-oxo-1,2-dihydropyridine-3-carboxamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 352.81 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), N-benzyl-1-(3-chlorobenzyl)-2-oxo-1,2-dihydropyridine-3-carboxamide 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.
