Chemical Structure

1-((4-Bromobenzylidene)amino)-4-(4-nitrobenzylidene)-2-phenyl-1H-imidazol-5(4H)-one CAS 126245-05-4 chemical structure

Description

The occurrence of 1-((4-Bromobenzylidene)amino)-4-(4-nitrobenzylidene)-2-phenyl-1H-imidazol-5(4H)-one is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 1-((4-Bromobenzylidene)amino)-4-(4-nitrobenzylidene)-2-phenyl-1H-imidazol-5(4H)-one (CAS 126245-05-4), a certified reference material (molecular formula C23H15BrN4O3, MW 475.29 g/mol) for analytical method development and quality control.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution, 1-((4-Bromobenzylidene)amino)-4-(4-nitrobenzylidene)-2-phenyl-1H-imidazol-5(4H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 475.29 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.

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.
