Chemical Structure
Description
The molecular framework of 4,4',4'',4''',4'''',4'''''-(benzene-1,2,3,4,5,6-hexaylhexakis(ethyne-2,1-diyl))hexabenzoic acid (C60H30O12) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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).
