The molecular framework of 1,3-Benzenedicarboxylic acid, polymer with 2,2-dimethyl-1,3-propanediol, ethenylbenzene, 2,5-furandione and 1,2-propanediol (C8H6O4C8H8C5H12O2C4H2O3C3H8O2) 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).
