Chemical Structure
Description
The molecular framework of 9-(2,4-Dichlorophenyl)-6,7-dimethoxy-1H,3H,4H,9H-furo[3,4-b]quinolin-1-one (C19H15Cl2NO4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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).
9-(2,4-Dichlorophenyl)-6,7-dimethoxy-1H,3H,4H,9H-furo[3,4-b]quinolin-1-one (CAS 900014-92-8) is a high-purity analytical reference standard with the molecular formula C19H15Cl2NO4 and a molecular weight of 392.23 g/mol.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
