Chemical Structure
Description
The occurrence of 3,4-Dihydroxytetrahydrothiophene 1,1-dioxide is closely related to a carbohydrate-derived structure, a sulfone group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3,4-Dihydroxytetrahydrothiophene 1,1-dioxide (CAS 33967-48-5), molecular formula C4H8O4S and molecular weight 152.17 g/mol, is a CATO reference standard with documented purity and traceability.
3,4-Dihydroxytetrahydrothiophene 1,1-dioxide (C4H8O4S) contains a carbohydrate-derived structure, a sulfone group. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
