Chemical Structure
Description
The molecular framework of 7,8-Dihydroxy-6-methoxy-3-(2-methylbut-3-en-2-yl)-2H-chromen-2-one (C15H16O5) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional 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).
7,8-Dihydroxy-6-methoxy-3-(2-methylbut-3-en-2-yl)-2H-chromen-2-one (CAS 82667-98-9), molecular formula C15H16O5 and molecular weight 276.28 g/mol, is a CATO reference standard with documented purity and traceability.
