Trifluoroacetic anhydride (TFAA) is the acid anhydride of trifluoroacetic acid. In particular trifluoroacetic anhydride is the perfluorinated derivative of acetic anhydride. Like many acid anhydrides it may be used to introduce the corresponding trifluoroacetyl group. The corresponding trifluoroacetyl chloride is a gas making it inconvenient to work with. Trifluoroacetic anhydride is the recommended desiccant for trifluoroacetic acid.
