Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Ethoxyethyl trifluoromethanesulfonate.
2-Ethoxyethyl trifluoromethanesulfonate (CAS 851536-76-0) is a high-purity analytical reference standard with the molecular formula C5H9F3O4S and a molecular weight of 222.18 g/mol.
2-Ethoxyethyl trifluoromethanesulfonate (C5H9F3O4S) 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.
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.
