N-(3-(2,4-dichlorobenzyl)-4-hydroxy-2-oxopyridin-1(2H)-yl)-1-methyl-1H-pyrrole-2-carboxamide (CAS 478045-93-1) is a high-purity analytical reference standard with the molecular formula C18H15Cl2N3O3 and a molecular weight of 392.24 g/mol.
The molecular framework of N-(3-(2,4-dichlorobenzyl)-4-hydroxy-2-oxopyridin-1(2H)-yl)-1-methyl-1H-pyrrole-2-carboxamide (C18H15Cl2N3O3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
