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.
(2Z)-N-[4-(1H-1,3-Benzodiazol-2-yl)phenyl]-2-[(2,3-dimethylphenyl)imino]-2H-chromene-3-carboxamide (CAS 478342-85-7) is a high-purity analytical reference standard with the molecular formula C31H24N4O2 and a molecular weight of 484.55 g/mol.
Structurally, (2Z)-N-[4-(1H-1,3-Benzodiazol-2-yl)phenyl]-2-[(2,3-dimethylphenyl)imino]-2H-chromene-3-carboxamide (C31H24N4O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 22.0, corresponding to approximately 22 ring(s) or double-bond equivalent(s). With a molecular weight of 484.55 g/mol, it falls into the moderately-high-molecular-weight range. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
