Chemical Structure
Description
5-Ethyl 2-methyl 4-isopropyl-3-methyl-6H-thieno[2,3-b]pyrrole-2,5-dicarboxylate (CAS 2852760-92-8) is a high-purity analytical reference standard with the molecular formula C15H19NO4S and a molecular weight of 309.38 g/mol.
Based on its molecular formula C15H19NO4S, 5-Ethyl 2-methyl 4-isopropyl-3-methyl-6H-thieno[2,3-b]pyrrole-2,5-dicarboxylate contains a flavonoid core, 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 309.38 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).
