Chemical Structure

9-(3,4-Dimethoxyphenyl)-6,7-dimethoxyfuro[3,4-b]quinolin-1(3H)-one CAS 161493-22-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 381.38 g/mol gives 9-(3,4-Dimethoxyphenyl)-6,7-dimethoxyfuro[3,4-b]quinolin-1(3H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

9-(3,4-Dimethoxyphenyl)-6,7-dimethoxyfuro[3,4-b]quinolin-1(3H)-one (CAS 161493-22-7), molecular formula C21H19NO6 and molecular weight 381.38 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 9-(3,4-Dimethoxyphenyl)-6,7-dimethoxyfuro[3,4-b]quinolin-1(3H)-one (C21H19NO6) 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.
