Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
N-benzyl-5-chloro-1-(2,4-dichlorobenzyl)-6-oxo-1,6-dihydropyridine-3-carboxamide (CAS 242472-03-3) is a high-purity analytical reference standard with the molecular formula C20H15Cl3N2O2 and a molecular weight of 421.70 g/mol.
The molecular framework of N-benzyl-5-chloro-1-(2,4-dichlorobenzyl)-6-oxo-1,6-dihydropyridine-3-carboxamide (C20H15Cl3N2O2) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
