TFA – Strong Acid for Peptide Cleavage

In peptide synthesis area, trifluoroacetic acid (TFA) is mostly used for cleaving the peptide from the solid support and deprotecting some protecting groups of the side chains. TFA shows many convenient properties such as high volatility, good solubility in organic solvents, and easy availablility in anhydrous form.
