Trifluoroacetic acid

Thermo Scientific Pierce Trifluoroacetic Acid (TFA), Sequencing grade is manufactured and tested to meet strict specifications that ensure superior performance for use as an ion-pairing agent in reverse-phase peptide separations.


  • High purity and exceptional clarity
  • High-performance packaging
  • Economical convenience


For complex peptide separations, varying mobile phase composition on the same column can change selectivity enough to resolve peptides that would otherwise overlap


Manufactured and tested to meet strict specifications that ensure superior performance for use as an ion-pairing agent in reverse-phase peptide separations.


The TFA concentration is usually specified as 0.1% for reverse-phase HPLC of peptides. For reproducible separations from run-to-run or from lab-to-lab, it is essential to make concentrations the same.


Formulation: Clear, colorless liquid of TFA (at least 99.5% pure; zero aldehyde; low water; low absorbance)
Sufficient For: Sequencing and liquid chromatography applications

Formula: C₂HF₃O₂
MDL Number: MFCD00004169
CAS Number: 76-05-1
