Chemical Structure

4-(((1H-Indol-3-yl)methylene)amino)-9-methoxy-7H-furo[3,2-g]chromen-7-one CAS 78439-81-3 chemical structure

Description

The molecular framework of 4-(((1H-Indol-3-yl)methylene)amino)-9-methoxy-7H-furo[3,2-g]chromen-7-one (C21H14N2O4) 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).

4-(((1H-Indol-3-yl)methylene)amino)-9-methoxy-7H-furo[3,2-g]chromen-7-one (CAS 78439-81-3) is a high-purity analytical reference standard with the molecular formula C21H14N2O4 and a molecular weight of 358.35 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.
