Chemical Structure
Description
The occurrence of Perfluoro-n-octanesulfonic acid-13C4 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.
Perfluoro-n-octanesulfonic acid-13C4 (CAS 960354-19-2) is a high-purity analytical reference standard with the molecular formula C4[13C]4HF17O3S and a molecular weight of 504.10 g/mol.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, Perfluoro-n-octanesulfonic acid-13C4 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 504.10 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), Perfluoro-n-octanesulfonic acid-13C4 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.
