Description

Compared with other compounds in its class, the molecular weight of 704.51 g/mol gives Bis(4-tert-butylphenyl)iodonium perfluoro-1-butanesulfonic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Bis(4-tert-butylphenyl)iodonium perfluoro-1-butanesulfonic acid (CAS 194999-85-4) is a high-purity analytical reference standard with the molecular formula C20H38IC4F9O3S and a molecular weight of 704.51 g/mol.

Bis(4-tert-butylphenyl)iodonium perfluoro-1-butanesulfonic acid (C20H38IC4F9O3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/iodine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
