Chemical Structure
Description
As a certified reference material (CRM), 2-methylbutane-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.
2-methylbutane-1-sulfonyl fluoride (CAS 1311315-63-5), molecular formula C5H11FO2S and molecular weight 154.20 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C5H11FO2S, 2-methylbutane-1-sulfonyl fluoride contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 154.20 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
