A fluorinated anionic surfactant acid, 1H,1H,2H,2H-Perfluorohexanesulfonic Acid belongs to the per- and polyfluoroalkyl substance group and is handled as an industrial and environmental reference material. The molecule pairs a perfluorinated chain with a terminal sulfonic acid group, giving the formula C6H5F9O3S and a molecular weight of 328.15, and it is an off-white solid. Laboratories working on fluorochemical residue screening, migration testing or method development use standards of this kind to assign retention times, verify response factors and confirm identity in LC-MS/MS runs where an authenticated calibrant is essential, whether the calibration is external or based on isotope dilution. Storage is at room temperature and transport is likewise at room temperature, which keeps handling simpler than for cold-chain analytes. Milligram pack sizes from 1 mg to 50 mg appear in the list, alongside 0.9 mL and 1.5 mL presentations. Requests for a quotation or the technical file can be made via the enquiry form.
