2-Amino-4-(3-((2,4-difluorophenoxy)methyl)-4-methoxyphenyl)-7-methyl-5-oxo-4H,5H-pyrano[4,3-b]pyran-3-carbonitrile (CAS 329737-37-3), molecular formula C24H18F2N2O5 and molecular weight 452.41 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C24H18F2N2O5, 2-Amino-4-(3-((2,4-difluorophenoxy)methyl)-4-methoxyphenyl)-7-methyl-5-oxo-4H,5H-pyrano[4,3-b]pyran-3-carbonitrile contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 452.41 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.
