Applications
The combination of properties like solubility in most of the solvents, volatility, catalytic property, and strong acidity with non-oxidizing nature makes it a widely used reagent in organic synthesis. Trifluoroacetic acid is an important building block in the synthesis of pharmaceuticals, agrochemicals and performance products. It is a precursor to many fluorinated compounds, and widely used in peptide synthesis and other organic transformations involving deprotection of t-BOC group. TFA finds use as an ion pairing agent in liquid chromatography, as a solvent in NMR spectroscopy and as a calibrant in mass spectrometry.

Solubility
Miscible with ether, acetone, ethanol, benzene, hexane and carbon tetrachloride.

Notes
Trifluoroacetic acid (TFA) is a stable, hygroscopic, volatile and low-boiling organic acid. Storage in a cool place is recommended.
