Chemical Structure
Description
The occurrence of (4-Phenylthiophenyl)diphenylsulfonium triflate is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(4-Phenylthiophenyl)diphenylsulfonium triflate (CAS 111281-12-0) is a high-purity analytical reference standard with the molecular formula C24H43S2CF3O3S and a molecular weight of 544.79 g/mol.
Based on its molecular formula C24H43S2CF3O3S, (4-Phenylthiophenyl)diphenylsulfonium triflate contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 544.79 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.
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.
