Chemical Structure
Description
The molecular framework of 1,1-Dioxido-3,6-dihydro-2H-thiopyran-4-yl trifluoromethanesulfonate (C6H7F3O5S2) is characterized by a carbohydrate-derived structure, a sulfone group, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
