Chemical Structure
Description
The molecular framework of 1-(2,6-Dichlorobenzyl)-6-oxo-N-propyl-1,6-dihydropyridine-3-carboxamide (C16H16Cl2N2O2) is characterized by a nitrogen-containing heterocyclic scaffold, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
1-(2,6-Dichlorobenzyl)-6-oxo-N-propyl-1,6-dihydropyridine-3-carboxamide (CAS 339008-69-4) is a high-purity analytical reference standard with the molecular formula C16H16Cl2N2O2 and a molecular weight of 339.22 g/mol.
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.
As a certified reference material (CRM), 1-(2,6-Dichlorobenzyl)-6-oxo-N-propyl-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.
