(Z)-1,4-Dimethoxy-3-(4-methoxypyridin-1-ium-1-yl)-1,4-dioxobut-2-ene-2-thiolate CAS 2833718-09-3

Description

Based on its molecular formula C12H13NO5S, (Z)-1,4-Dimethoxy-3-(4-methoxypyridin-1-ium-1-yl)-1,4-dioxobut-2-ene-2-thiolate contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 283.30 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).
