Chemical Structure
Description
898769-84-1 Ethyl 4-{4-[(morpholin-4-yl)methyl]benzoyl}benzoate DTXSID00642626 (CAS 898769-84-1) is a high-purity analytical reference standard with the molecular formula C21H23NO4 and a molecular weight of 353.41 g/mol.
The molecular framework of 898769-84-1 Ethyl 4-{4-[(morpholin-4-yl)methyl]benzoyl}benzoate DTXSID00642626 (C21H23NO4) 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.
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.
