WebAdditionally, some of these strong acids have unfavorable oxidizing properties. Many laboratories use trifluoroacetic acid (TFA) in order to form ion pairs with peptides and proteins and to improve subsequent HPLC separation; however, TFA causes strong ion suppression of the analyte during MS detection and may as well contaminate the mass … WebDoing the math, we find that the pK a of acetic acid is 4.8. The use of pK a values allows us to express the acidity of common compounds and functional groups on a numerical scale …
Environmental Risk Assessment of Trifluoroacetic Acid
WebApr 11, 2024 · Trifluoroacetic acid (TFA) is an analogue of acetic acid with the three hydrogen atoms replaced by three fluorine atoms. It has a vinegar-like odor and is a strong acid, a good solvent and has excellent reactive properties. The specific gravity of liquid TFA is 1.48 and it boils at 72 °C. Trifluoroacetic Acid is a solvent that is used in the ... WebTrifluoroacetic acid (TFA) is a colorless, fuming and corrosive organofluorine compound that has an odor like vinegar. Almost 100,000-fold more acidic than acetic acid, TFA is widely used in organic chemistry.
