Chemical Structure
Description
The molecular framework of (2E)-5,6-dimethoxy-2-[(3-phenoxyphenyl)methylidene]-2,3-dihydro-1H-inden-1-one 268563-94-6 MS-9201 (C24H20O4) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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).
