Description
CATO supplies 1-(3,4-Dichlorobenzyl)-6-oxo-N-phenyl-1,6-dihydropyridine-3-carboxamide (CAS 338781-38-7), a certified reference material (molecular formula C19H14Cl2N2O2, MW 373.23 g/mol) for analytical method development and quality control.
1-(3,4-Dichlorobenzyl)-6-oxo-N-phenyl-1,6-dihydropyridine-3-carboxamide (C19H14Cl2N2O2) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), 1-(3,4-Dichlorobenzyl)-6-oxo-N-phenyl-1,6-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.
