Chemical Structure
Description
As a certified reference material (CRM), Perfluoro-1-butanesulfonyl 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.
Perfluoro-1-butanesulfonyl Fluoride (CAS 375-72-4), molecular formula C4F10O2S and molecular weight 302.09 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Perfluoro-1-butanesulfonyl Fluoride (C4F10O2S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
