The product is a high purity reagent for HPLC. In the experiment of reverse phase chromatography for isolation of peptides and proteins, using trifluoroacetic acid (TFA) as the ion-pairing reagents is a common approach. Trifluoroacetic acid in the mobile phase can improve the peak shape and overcome the problem of the peak broadening and trailing issue through interaction with hydrophobic bonded phase and residual polar surface in a variety of models.
