As a certified reference material (CRM), 3-vinyl-2,5-dihydrothiophene1,1-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.
3-vinyl-2,5-dihydrothiophene1,1-Dioxide (CAS 108919-89-7), molecular formula C6H8O2S and molecular weight 144.19 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 3-vinyl-2,5-dihydrothiophene1,1-Dioxide is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 144.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
