Chemical Structure
Description
1-(4-tert-butylphenyl)tetrahydrothiophen-1-ium;trifluoromethanesulfonate (CAS 220155-95-3) is a high-purity analytical reference standard with the molecular formula C14H21SCF3O3S and a molecular weight of 370.44 g/mol.
1-(4-tert-butylphenyl)tetrahydrothiophen-1-ium;trifluoromethanesulfonate (C14H21SCF3O3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. 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.
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.
