Compared with other compounds in its class, the molecular weight of 126.15 g/mol gives Propane-1-sulfonyl fluoride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Propane-1-sulfonyl fluoride (CAS 762-69-6), molecular formula C3H7FO2S and molecular weight 126.15 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, fluorine substitution, Propane-1-sulfonyl fluoride is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 126.15 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), Propane-1-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.
