General description
Trifluoroacetic acid (TFA) is a fluorinated acetic acid. It is widely used as trifluoromethylating reagent for trifluoromethylation of aromatic compounds.
Application
Trifluoroacetic acid (TFA) may be used in the following studies:
- Preparation of TFA reagent for the estimation of serum vitamin A.
- To compose the binary solvent system for the isolation of large denatured peptides by reverse phase high performance liquid chromatography.
- A mobile-phase additive for liquid chromatography-mass spectrometry (LC-MS) analysis.
- Preparation of artemisinin under optimized reaction conditions.

Direct trifluoromethylation of arenes using TFA as the trifluoromethylating reagent was achieved with Ag as the catalyst. This reaction not only provides a new protocol for aryl C-H trifluoromethylation, but the generation of CF3· from TFA may prove useful in
