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 organic solvents, and its strength as an acid. TFA is … 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 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 See more WebApr 1, 2024 · Acetic acid's density is 1.053 g/mol at room temperature in the liquid form, though it can also exist as a solid. The pKa of acetic acid is 4.76, which is the pH value at which half of the acid will be intact and the other half in the ionic form. The formula for the acetate ion (the conjugate base of acetic acid) is CH 3 COO–.

WebTrifluoroacetic anhydride can undergo reaction with deoxyguanosine in pyridine to give the corresponding 6-substituted-2′-deoxyguanosine derivatives. It can also react with urea … WebTrifluoroacetic acid (TFA) is the simplest stable perfluorinated carboxylic acid chemical compound, with the formula CF3CO2H. It is a strong carboxylic acid due to the influence of the electronegative trifluoromethyl group. TFA is almost 100,000-fold more acidic than acetic acid. TFA is widely used in organic chemistry.
