Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, (2Z)-N-[4-(1H-1,3-Benzodiazol-2-yl)phenyl]-2-[(4-ethoxyphenyl)imino]-2H-chromene-3-carboxamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 500.55 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).
(2Z)-N-[4-(1H-1,3-Benzodiazol-2-yl)phenyl]-2-[(4-ethoxyphenyl)imino]-2H-chromene-3-carboxamide (CAS 478342-68-6), molecular formula C31H24N4O3 and molecular weight 500.55 g/mol, is a CATO reference standard with documented purity and traceability.
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.
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.
