Chemical Structure
Description
The occurrence of Potassium 11-Chloroeicosafluoro-3-oxaundecane-1-sulfonate is closely related to a salt form, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Potassium 11-Chloroeicosafluoro-3-oxaundecane-1-sulfonate (CAS 83329-89-9) is a high-purity analytical reference standard with the molecular formula C10ClF20O4SK and a molecular weight of 670.67 g/mol.
Structurally, Potassium 11-Chloroeicosafluoro-3-oxaundecane-1-sulfonate (C10ClF20O4SK) contains a salt form, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 0.5, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 670.67 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
