Chemical Structure
Description
N-(2-((4-chloro-3-nitrophenyl)amino)-2-oxoethyl)-N-cyclohexyl-3-nitrobenzamide (CAS 332156-19-1), molecular formula C21H21ClN4O6 and molecular weight 460.87 g/mol, is a CATO reference standard with documented purity and traceability.
N-(2-((4-chloro-3-nitrophenyl)amino)-2-oxoethyl)-N-cyclohexyl-3-nitrobenzamide (C21H21ClN4O6) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), N-(2-((4-chloro-3-nitrophenyl)amino)-2-oxoethyl)-N-cyclohexyl-3-nitrobenzamide 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.
