5,6-dimethoxybenzothiophene-2-carboxylic acid CAS 23046-03-9

Description

Based on its molecular formula C11H18O4S, 5,6-dimethoxybenzothiophene-2-carboxylic acid contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 246.32 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).
