Chemical Structure
Description
The occurrence of Isopropyldiphenylsulfonium tetrafluoroborate is closely related to sulfur-containing functionality, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Isopropyldiphenylsulfonium tetrafluoroborate (CAS 40447-58-3), molecular formula C15H17SBF4 and molecular weight 316.16 g/mol, is a CATO reference standard with documented purity and traceability.
Isopropyldiphenylsulfonium tetrafluoroborate (C15H17SBF4) contains sulfur-containing functionality, fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
