Description

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.

Packaging
