Chemical Structure
Description
CATO supplies Dimesityl(trifluoromethyl)sulfonium trifluoromethanesulfonate (CAS 1895006-01-5), a certified reference material (molecular formula C19H22F3SCF3O3S, MW 488.50 g/mol) for analytical method development and quality control.
Dimesityl(trifluoromethyl)sulfonium trifluoromethanesulfonate (C19H22F3SCF3O3S) contains a steroid core, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, 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.
