Chemical Structure
Description
The occurrence of (2Z)-N-(4-Bromophenyl)-2-[(1E)-{[(2,4-dichlorophenyl)methoxy]imino}methyl]-3-(dimethylamino)prop-2-enamide is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(2Z)-N-(4-Bromophenyl)-2-[(1E)-{[(2,4-dichlorophenyl)methoxy]imino}methyl]-3-(dimethylamino)prop-2-enamide (CAS 320417-96-7), molecular formula C19H18BrCl2N3O2 and molecular weight 471.18 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (2Z)-N-(4-Bromophenyl)-2-[(1E)-{[(2,4-dichlorophenyl)methoxy]imino}methyl]-3-(dimethylamino)prop-2-enamide (C19H18BrCl2N3O2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
