General description

1,1,1,3,3,3-Hexafluoro-2-propanol(HFIP) is a thermally stable, highly polar, UV-transparent solvent that is misciblewith water and many polar organic solvents. It is used as a mobile phaseadditive in liquid chromatography-mass spectrometry (LC-MS) method to improveseparation and detection.

Application

1,1,1,3,3,3-Hexafluoro-2-propanol can be used as a:
  • Buffer additive for LC-ESI-MS to separate acidic and basic compounds.
  • Eluent additive in the UHPLC-MS/MS method to improve the chromatographic separation of basic and zwitterionic compounds.
