Chemical Structure
Description
The molecular framework of 3-Acetyl-1-(4-methoxyphenyl)-2-methyl-1H-indol-5-yl acetate (C20H19NO4) 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).
3-Acetyl-1-(4-methoxyphenyl)-2-methyl-1H-indol-5-yl acetate (CAS 119953-11-6) is a high-purity analytical reference standard with the molecular formula C20H19NO4 and a molecular weight of 337.37 g/mol.
