Chemical Structure
Description
The occurrence of Potassium Perfluoropentanesulfonate 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.
Potassium Perfluoropentanesulfonate (CAS 3872-25-1) is a high-purity analytical reference standard with the molecular formula C5F11O3SK and a molecular weight of 388.19 g/mol.
Potassium Perfluoropentanesulfonate (C5F11O3SK) 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.
