CATO supplies Trifluoro-methanesulfonic acid bis(1-methylethyl)(1,1,2-trimethylpropyl)silyl ester (CAS 561322-36-9), a certified reference material (molecular formula C13H27F3O3SSi, MW 348.50 g/mol) for analytical method development and quality control.
Based on its molecular formula C13H27F3O3SSi, Trifluoro-methanesulfonic acid bis(1-methylethyl)(1,1,2-trimethylpropyl)silyl ester contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 348.50 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
