Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 650.15 g/mol gives Perfluoroundecanesulfonic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Perfluoroundecanesulfonic acid (CAS 749786-16-1) is a high-purity analytical reference standard with the molecular formula C11HF23O3S and a molecular weight of 650.15 g/mol.
Structurally, Perfluoroundecanesulfonic acid (C11HF23O3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 0.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 650.15 g/mol, it falls into the high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
