Description
CATO supplies Potassium 2,2'-oxybis(1,1,2,2-tetrafluoroethanesulfonate) (CAS 104820-46-4), a certified reference material (molecular formula C4F8O7S2K, MW 415.24 g/mol) for analytical method development and quality control.
Owing to a carbohydrate-derived structure, a sulfone group, fluorine substitution, Potassium 2,2'-oxybis(1,1,2,2-tetrafluoroethanesulfonate) is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 415.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), Potassium 2,2'-oxybis(1,1,2,2-tetrafluoroethanesulfonate) 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.
