Chemical Structure
Description
N-(4-methoxybenzyl)-2-(3-oxo-3,4-dihydro-2H-benzo[b][1,4]oxazine-6-carbonyl)benzamide (CAS 861209-41-8) is a high-purity analytical reference standard with the molecular formula C24H20N2O5 and a molecular weight of 416.43 g/mol.
N-(4-methoxybenzyl)-2-(3-oxo-3,4-dihydro-2H-benzo[b][1,4]oxazine-6-carbonyl)benzamide (C24H20N2O5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
