N-(4-chlorobenzyl)-1-(3,4-dichlorobenzyl)-2-oxo-1,2-dihydropyridine-3-carboxamide (CAS 338754-40-8) is a high-purity analytical reference standard with the molecular formula C20H15Cl3N2O2 and a molecular weight of 421.70 g/mol.
N-(4-chlorobenzyl)-1-(3,4-dichlorobenzyl)-2-oxo-1,2-dihydropyridine-3-carboxamide (C20H15Cl3N2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures N-(4-chlorobenzyl)-1-(3,4-dichlorobenzyl)-2-oxo-1,2-dihydropyridine-3-carboxamide 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.
