Chemical Structure
Description
Mesityl(p-tolyl)iodonium trifluoromethanesulfonate (CAS 1204518-02-4) is a high-purity analytical reference standard with the molecular formula C16H18ICF3O3S and a molecular weight of 486.28 g/mol.
Based on its molecular formula C16H18ICF3O3S, Mesityl(p-tolyl)iodonium trifluoromethanesulfonate contains a steroid core, a sulfone group, a hydroxyl group, an ether linkage, fluorine/iodine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 486.28 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
