Chemical Structure
Description
The occurrence of Nonafluoro-1-Butanesulfonic Acid is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Nonafluoro-1-Butanesulfonic Acid (CAS 375-73-5), molecular formula C4HF9O3S and molecular weight 300.10 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C4HF9O3S, Nonafluoro-1-Butanesulfonic Acid 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 300.10 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.
As a certified reference material (CRM), Nonafluoro-1-Butanesulfonic Acid 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.
