Chemical Structure

1,2,3,4,6-pentagalloylglucose CAS 14937-32-7 chemical structure

Description

Based on its molecular formula C41H32O26, 1,2,3,4,6-pentagalloylglucose contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 940.68 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).
