Chemical Structure
Description
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.
N-(4-Fluorophenyl)-2-nitro-N-{[3-oxo-2-benzofuran-1(3H)-yliden]methyl}ethanimidohydrazide (CAS 477852-79-2) is a high-purity analytical reference standard with the molecular formula C17H13FN4O4 and a molecular weight of 356.31 g/mol.
N-(4-Fluorophenyl)-2-nitro-N-{[3-oxo-2-benzofuran-1(3H)-yliden]methyl}ethanimidohydrazide (C17H13FN4O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
