Chemical Structure
Description
3-[(2,6-Dichlorophenyl)methyl]-1-[(4-methoxyphenyl)methyl]-2-methyl-1,4-dihydropyridin-4-one (CAS 339017-32-2), molecular formula C21H19Cl2NO2 and molecular weight 388.29 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-[(2,6-Dichlorophenyl)methyl]-1-[(4-methoxyphenyl)methyl]-2-methyl-1,4-dihydropyridin-4-one (C21H19Cl2NO2) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), 3-[(2,6-Dichlorophenyl)methyl]-1-[(4-methoxyphenyl)methyl]-2-methyl-1,4-dihydropyridin-4-one 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.
