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 atoms and is a colorless liquid with a vinegar-like odor. TFA is a stronger acid than acetic acid, having an acid … See more TFA is prepared industrially by the electrofluorination of acetyl chloride or acetic anhydride, followed by hydrolysis of the resulting trifluoroacetyl fluoride: CH 3COCl + 4 HF → CF 3COF + 3 H 2 + HCl CF 3COF + H 2O → … 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 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 … 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 not labile. Only if heated or treated with ultrasonic waves will it decompose into hydrofluoric acid. TFA is harmful when … See more • Fluoroacetic acid – highly toxic but naturally occurring rodenticide CH2FCOOH • Difluoroacetic acid • Trichloroacetic acid, the chlorinated analog See more
