Description

Used to cleave peptide blocking groupsThe 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.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
