CATO supplies N-{5-acetyl-6-[(E)-2-{[(3-methoxyphenyl)methyl]amino}ethenyl]-2-oxo-2H-pyran-3-yl}benzamide (CAS 294853-49-9), a certified reference material (molecular formula C24H22N2O5, MW 418.44 g/mol) for analytical method development and quality control.
Based on its molecular formula C24H22N2O5, N-{5-acetyl-6-[(E)-2-{[(3-methoxyphenyl)methyl]amino}ethenyl]-2-oxo-2H-pyran-3-yl}benzamide contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 418.44 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.
