Chemical Structure
Description
5,5-difluoro-1,3,2-dioxathiane 2,2-dioxide (CAS 1215071-15-0), molecular formula C3H4F2O4S and molecular weight 174.12 g/mol, is a CATO reference standard with documented purity and traceability.
5,5-difluoro-1,3,2-dioxathiane 2,2-dioxide (C3H4F2O4S) contains a sulfone group, a carboxylic acid group, an ether linkage, 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 5,5-difluoro-1,3,2-dioxathiane 2,2-dioxide 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.
