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 supplies N-benzyl-4-nitro-N-(2-oxo-2-((2,4,6-trichlorophenyl)amino)ethyl)benzamide (CAS 332163-25-4), a certified reference material (molecular formula C22H16Cl3N3O4, MW 492.74 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, N-benzyl-4-nitro-N-(2-oxo-2-((2,4,6-trichlorophenyl)amino)ethyl)benzamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 492.74 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
