    General description

    Trifluoroacetic acid (TFA) is a fluorinated acetic acid. It is widely used as trifluoromethylating reagent for trifluoromethylation of aromatic compounds.[4]

    Application

    Trifluoroacetic acid (TFA) may be used in the following studies:
    • Preparation of TFA reagent for the estimation of serum vitamin A.[3]
    • To compose the binary solvent system for the isolation of large denatured peptides by reverse phase high performance liquid chromatography.[2]
    • A mobile-phase additive for liquid chromatography-mass spectrometry (LC-MS) analysis.[1]
    • Preparation of artemisinin under optimized reaction conditions.[5]
