Chemical Structure
Description
(4-Fluorophenyl)diphenylsulfonium trifluoromethanesulfonate (C18H14FSCF3O3S) contains a steroid core, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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).
(4-Fluorophenyl)diphenylsulfonium trifluoromethanesulfonate (CAS 154093-57-9), molecular formula C18H14FSCF3O3S and molecular weight 430.43 g/mol, is a CATO reference standard with documented purity and traceability.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
