Chemical Structure
Description
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.
Di-tert-butyl(isobutyl)silyl trifluoromethanesulfonate (CAS 1314639-86-5), molecular formula C13H27F3O3SSi and molecular weight 348.50 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C13H27F3O3SSi, Di-tert-butyl(isobutyl)silyl trifluoromethanesulfonate 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. 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.
