Application: | Perfluorohexanoic acid may be used as an analytical reference standard for the determination of the analyte in the following: • biological samples using high-performance liquid chromatography (HPLC) with fluorescence detection • dissolved/particulate phases of wastewater and sewage sludge using liquid chromatography-electrospr • whole blood samples using high-performance liquid chromatography- negative electrospray single quadrupole mass spectrometry (HPLC/ES-MS) |
General description: | Perfluorohexanoic acid belonging to the class of perfluorinated carboxylic acids (PFCAs), with a 5-carbon perfluoroalkyl chain, was developed as an alternative to the environmental pollutant, perfluorooctanoic acid (PFOA). The degradation of perfluorohexanoic acid is complex, due to the stability of the carbon-fluorine (C-F) bond. It is most commonly used as a wetting agent, corrosion inhibitor, lubricant, and foam fire extinguishant. |
