The occurrence of (E)-2-(4-benzoylphenyl)-2-(4-chlorophenyl)-N-((methoxyimino)methyl)acetamide is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(E)-2-(4-benzoylphenyl)-2-(4-chlorophenyl)-N-((methoxyimino)methyl)acetamide (CAS 339012-89-4) is a high-purity analytical reference standard with the molecular formula C23H19ClN2O3 and a molecular weight of 406.86 g/mol.
The molecular framework of (E)-2-(4-benzoylphenyl)-2-(4-chlorophenyl)-N-((methoxyimino)methyl)acetamide (C23H19ClN2O3) 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).
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), (E)-2-(4-benzoylphenyl)-2-(4-chlorophenyl)-N-((methoxyimino)methyl)acetamide 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.
