(E)-N-((((4-chlorobenzyl)oxy)imino)methyl)-2-(4-chlorophenoxy)-4-methoxynicotinamide (CAS 339102-12-4), molecular formula C21H17Cl2N3O4 and molecular weight 446.28 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C21H17Cl2N3O4, (E)-N-((((4-chlorobenzyl)oxy)imino)methyl)-2-(4-chlorophenoxy)-4-methoxynicotinamide contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 446.28 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
