(2Z)-N-[4-(1H-1,3-Benzodiazol-2-yl)phenyl]-2-[(2,4-dimethoxyphenyl)imino]-2H-chromene-3-carboxamide (CAS 478342-70-0) is a high-purity analytical reference standard with the molecular formula C31H24N4O4 and a molecular weight of 516.55 g/mol.
The molecular framework of (2Z)-N-[4-(1H-1,3-Benzodiazol-2-yl)phenyl]-2-[(2,4-dimethoxyphenyl)imino]-2H-chromene-3-carboxamide (C31H24N4O4) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
