CATO supplies 1-(3,4-Dichlorobenzyl)-2-oxo-N-phenyl-1,2-dihydropyridine-3-carboxamide (CAS 338754-33-9), a certified reference material (molecular formula C19H14Cl2N2O2, MW 373.23 g/mol) for analytical method development and quality control.
1-(3,4-Dichlorobenzyl)-2-oxo-N-phenyl-1,2-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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
