Description
CATO supplies 2,6-Dichloro-N-{1-[(2,6-dichlorophenyl)methyl]-2-oxo-1,2-dihydropyridin-3-yl}benzamide (CAS 338784-15-9), a certified reference material (molecular formula C19H12Cl4N2O2, MW 442.12 g/mol) for analytical method development and quality control.
2,6-Dichloro-N-{1-[(2,6-dichlorophenyl)methyl]-2-oxo-1,2-dihydropyridin-3-yl}benzamide (C19H12Cl4N2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 2,6-Dichloro-N-{1-[(2,6-dichlorophenyl)methyl]-2-oxo-1,2-dihydropyridin-3-yl}benzamide 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.
