Chemical Structure
Description
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.
CATO supplies 1-[(3,4-Dichlorophenyl)methyl]-5-(morpholine-4-carbonyl)-1,2-dihydropyridin-2-one (CAS 338781-26-3), a certified reference material (molecular formula C17H16Cl2N2O3, MW 367.23 g/mol) for analytical method development and quality control.
The molecular framework of 1-[(3,4-Dichlorophenyl)methyl]-5-(morpholine-4-carbonyl)-1,2-dihydropyridin-2-one (C17H16Cl2N2O3) 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).
As a certified reference material (CRM), 1-[(3,4-Dichlorophenyl)methyl]-5-(morpholine-4-carbonyl)-1,2-dihydropyridin-2-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.
