TFA was claimed to occur naturally in sea water, but only in small concentrations at about 200 ng per liter. However, a review paper from 2024 concludes that there is insufficient evidence that TFA occurs naturally, especially without a reasonable mechanism of formation. In the environment, it is also formed, … See more Trifluoroacetic acid (TFA) is an organofluorine compound with the chemical formula CF3CO2H. It is a structural analogue of acetic acid with all three of the acetyl group's hydrogen atoms replaced by fluorine … See more TFA is prepared industrially by the electrofluorination of acetyl chloride or acetic anhydride, followed by hydrolysis of the resulting … See more Trifluoroacetic acid is a corrosive acid but it does not pose the hazards associated with hydrofluoric acid because the carbon-fluorine bond is … See more TFA is the precursor to many other fluorinated compounds such as trifluoroacetic anhydride, trifluoroperacetic acid, and 2,2,2-trifluoroethanol. It is a reagent used in organic synthesis because of a combination of convenient properties: volatility, solubility in … See more • Fluoroacetic acid – highly toxic but naturally occurring rodenticide CH2FCOOH • Difluoroacetic acid See more
