Chemical Structure
Description
As a certified reference material (CRM), Nonafluorobutanesulphonic acid hydrate 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.
CATO supplies Nonafluorobutanesulphonic acid hydrate (CAS 1185303-26-7), a certified reference material (molecular formula C4HF9O3SH2O, MW 318.11 g/mol) for analytical method development and quality control.
The molecular framework of Nonafluorobutanesulphonic acid hydrate (C4HF9O3SH2O) is characterized by a carbohydrate-derived structure, a sulfone group, 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.
