5-{5,6-dichloro-1-[(2,4-dichlorophenyl)methyl]-1H-1,3-benzodiazol-2-yl}-1,2-dihydropyridin-2-one CAS 338773-97-0

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.

5-{5,6-dichloro-1-[(2,4-dichlorophenyl)methyl]-1H-1,3-benzodiazol-2-yl}-1,2-dihydropyridin-2-one (CAS 338773-97-0), molecular formula C19H11Cl4N3O and molecular weight 439.12 g/mol, is a CATO reference standard with documented purity and traceability.

5-{5,6-dichloro-1-[(2,4-dichlorophenyl)methyl]-1H-1,3-benzodiazol-2-yl}-1,2-dihydropyridin-2-one (C19H11Cl4N3O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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).

As a certified reference material (CRM), 5-{5,6-dichloro-1-[(2,4-dichlorophenyl)methyl]-1H-1,3-benzodiazol-2-yl}-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.
