4353-77-9 trimethylsilyl sulfurochloridate trimethylsilylchlorosulfonate CAS 4353-77-9

Description

4353-77-9 trimethylsilyl sulfurochloridate trimethylsilylchlorosulfonate (C3H9ClO3SSi) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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.
