Chemical Structure
Description
Pentafluorophenyl Fluorosulfonate (CAS 60129-86-4), molecular formula C6F6O3S and molecular weight 266.12 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C6F6O3S, Pentafluorophenyl Fluorosulfonate contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 266.12 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
