  • Applications

    Sodium trifluoroacetate is the sodium salt of trifluoroacetic acid and is mainly used as a source of the trifluoroacetate counterion in organic synthesis and in formulation workflows. It serves as an intermediate/reagent in the preparation of trifluoroacetyl-containing compounds and can be employed to generate trifluoroacetate buffers for analytical chemistry and reaction media. The salt is sometimes used as a processing additive in polymers and coatings to modulate acidity and ionic strength, and may be encountered in chromatography and LC-MS workflows as part of buffer systems or sample-preparation steps. It can also function as a stable salt form for handling and shipping of trifluoroacetate-containing reagents, subject to local regulations.
