Chemical Structure
Description
4-((Isopropyldimethylsilyl)oxy)cyclohex-1-en-1-yl trifluoromethanesulfonate (C12H21F3O4SSi) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, 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.
4-((Isopropyldimethylsilyl)oxy)cyclohex-1-en-1-yl trifluoromethanesulfonate (CAS 1245648-54-7), molecular formula C12H21F3O4SSi and molecular weight 346.44 g/mol, is a CATO reference standard with documented purity and traceability.
