Chemical Structure
Description
CATO supplies 4-Fluoro-1,3,2-dioxathiolane 2-oxide (CAS 871838-01-6), a certified reference material (molecular formula C2H3FO3S, MW 126.11 g/mol) for analytical method development and quality control.
4-Fluoro-1,3,2-dioxathiolane 2-oxide (C2H3FO3S) contains a sulfone group, a carboxylic acid group, an ether linkage, 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.
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.
