Chemical Structure
Description
5,6,7,7a-tetrahydrothieno[3,2-c]pyridin-2(4H)-one 4-methylbenzenesulfonate (C7H8O3SC7H9NOS) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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).
5,6,7,7a-tetrahydrothieno[3,2-c]pyridin-2(4H)-one 4-methylbenzenesulfonate (CAS 952340-39-5) is a high-purity analytical reference standard with the molecular formula C7H8O3SC7H9NOS and a molecular weight of 327.41 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
