Chemical Structure
Description
The occurrence of 6-Oxo-4H-thieno[2,3-c]pyrrole-5(6H)-carbonyl chloride is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
6-Oxo-4H-thieno[2,3-c]pyrrole-5(6H)-carbonyl chloride (CAS 79472-38-1) is a high-purity analytical reference standard with the molecular formula C7H4ClNO2S and a molecular weight of 201.63 g/mol.
Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 6-Oxo-4H-thieno[2,3-c]pyrrole-5(6H)-carbonyl chloride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 201.63 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
