Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 318.09 g/mol gives 1,1,2,2-Tetrafluoro-2-(perfluoroethoxy)ethane-1-sulfonyl fluoride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1,1,2,2-Tetrafluoro-2-(perfluoroethoxy)ethane-1-sulfonyl fluoride (CAS 67990-78-7), a certified reference material (molecular formula C4F10O3S, MW 318.09 g/mol) for analytical method development and quality control.
The molecular framework of 1,1,2,2-Tetrafluoro-2-(perfluoroethoxy)ethane-1-sulfonyl fluoride (C4F10O3S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
