General description
Difluoroaceticacid is used in liquid chromatography-mass spectrometry applications. It is a volatile, low molecular-weight organic acid that improves the ionization and resolution of many molecules.
Application
- Acidifier in liquid chromatography (LC) experiments.
- Ion-pairing agent in the HILIC-MS (hydrophilic interaction liquid chromatography-mass spectrometry) analysis of intact pharmaceutical glycoproteins.
