3-Benzyl-5-[(1E)-{[(3-chlorophenyl)methoxy]imino}methyl]-1-[(2,4-dichlorophenyl)methyl]-4-hydroxy-1,2-dihydropyridin-2-one CAS 477888-14-5 chemical structure

Description

As a certified reference material (CRM), 3-Benzyl-5-[(1E)-{[(3-chlorophenyl)methoxy]imino}methyl]-1-[(2,4-dichlorophenyl)methyl]-4-hydroxy-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.

3-Benzyl-5-[(1E)-{[(3-chlorophenyl)methoxy]imino}methyl]-1-[(2,4-dichlorophenyl)methyl]-4-hydroxy-1,2-dihydropyridin-2-one (CAS 477888-14-5), molecular formula C27H21Cl3N2O3 and molecular weight 527.83 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 3-Benzyl-5-[(1E)-{[(3-chlorophenyl)methoxy]imino}methyl]-1-[(2,4-dichlorophenyl)methyl]-4-hydroxy-1,2-dihydropyridin-2-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 527.83 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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.
