Chemical Structure
Description
The molecular framework of 2,2'-(Benzofuran-2,7-diyl)bis(4,4,5,5-tetramethyl-1,3,2-dioxaborolane) (C20H28B2O5) 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).
