(2Z)-N-[4-(1H-1,3-Benzodiazol-2-yl)phenyl]-2-[(2,3-dimethylphenyl)imino]-8-methoxy-2H-chromene-3-carboxamide (CAS 478342-93-7), molecular formula C32H26N4O3 and molecular weight 514.57 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (2Z)-N-[4-(1H-1,3-Benzodiazol-2-yl)phenyl]-2-[(2,3-dimethylphenyl)imino]-8-methoxy-2H-chromene-3-carboxamide (C32H26N4O3) 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 514.57 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
