Chemical Structure
Description
Based on its molecular formula C8H6O4C8H8O3C4H2O3C3H8O2, 1,3-Benzenedicarboxylic acid, polymer with 2,5-furandione, 1,2-propanediol and 3a,4,7,7a-tetrahydro-1,3-isobenzofurandione contains a flavonoid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 492.43 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
