Chemical Structure
Description
2-(Trifluoromethoxy)ethyl trifluoromethanesulfonate (C4H4F6O4S) contains a carbohydrate-derived structure, a sulfone group, 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.
2-(Trifluoromethoxy)ethyl trifluoromethanesulfonate (CAS 329710-76-1) is a high-purity analytical reference standard with the molecular formula C4H4F6O4S and a molecular weight of 262.13 g/mol.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
