Chemical Structure
Description
As a certified reference material (CRM), 1,1-dioxo-1λ⁶-thiane-4-sulfonyl fluoride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
1,1-dioxo-1λ⁶-thiane-4-sulfonyl fluoride (CAS 1934486-23-3) is a high-purity analytical reference standard with the molecular formula C5H9FO4S2 and a molecular weight of 216.25 g/mol.
1,1-dioxo-1λ⁶-thiane-4-sulfonyl fluoride (C5H9FO4S2) contains a carbohydrate-derived structure, a sulfone group, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
