Chemical Structure

Ethyl 1H,3H-thieno[3,4-c]furan-4-carboxylate CAS 2103866-18-6 chemical structure

Description

Ethyl 1H,3H-thieno[3,4-c]furan-4-carboxylate (C9H10O3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Ethyl 1H,3H-thieno[3,4-c]furan-4-carboxylate (CAS 2103866-18-6), molecular formula C9H10O3S and molecular weight 198.24 g/mol, is a CATO reference standard with documented purity and traceability.
