Ethyl (11-oxo-10,11-dihydrodibenzo[b,f][1,4]oxazepin-2-yl)carbamate (CAS 331246-30-1) is a high-purity analytical reference standard with the molecular formula C16H14N2O4 and a molecular weight of 298.29 g/mol.
The molecular framework of Ethyl (11-oxo-10,11-dihydrodibenzo[b,f][1,4]oxazepin-2-yl)carbamate (C16H14N2O4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
