Perfluorohexanesulfonic acid-13C3 sodium salt (CAS 2708218-86-2) is a high-purity analytical reference standard with the molecular formula C3[13C]3F13O3S Na and a molecular weight of 398.06 g/mol.
Perfluorohexanesulfonic acid-13C3 sodium salt (C3[13C]3F13O3S Na) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), Perfluorohexanesulfonic acid-13C3 sodium salt 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.
