Chemical Structure
Description
The molecular framework of 4,4',4''-(Methylsilanetriyl)tribenzoic acid (C22H18O6Si) 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).
4,4',4''-(Methylsilanetriyl)tribenzoic acid (CAS 31825-52-2), molecular formula C22H18O6Si and molecular weight 406.46 g/mol, is a CATO reference standard with documented purity and traceability.
