Chemical Structure
Description
The occurrence of 1-((2-Chlorobenzylidene)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, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 1-((2-Chlorobenzylidene)amino)-4-(4-nitrobenzylidene)-2-phenyl-1H-imidazol-5(4H)-one (CAS 126293-47-8), a certified reference material (molecular formula C23H15ClN4O3, MW 430.84 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 1-((2-Chlorobenzylidene)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 430.84 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.
CATO manufactures 1-((2-Chlorobenzylidene)amino)-4-(4-nitrobenzylidene)-2-phenyl-1H-imidazol-5(4H)-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
