Trifluoroacetate () is a polyatomic ion, the anion that is the conjugate base of trifluoroacetic acid (CF<sub>3</sub>CO<sub>2</sub>H).
The salts containing the trifluoroacetate anion can be made by an acidâÂÂbase reaction between trifluoroacetic acid and a base, such as sodium hydroxide (NaOH) to give sodium trifluoroacetate (CF<sub>3</sub>COONa):
Trifluoroacetic acid is one of the shortest possible perfluoroalkyl substances (PFAS). It is suspected to be a persistent pollutant.
