Descripción

General description

Trifluoroacetic acid is a phytotoxic compound belonging to the class of perfluorinated acids (PFAs). It is an environmental contaminant, which contributes to the organo-fluorine burden in surface and ground waters.

Application

Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

Trifluoroacetic acid may be used as a modifier in high performance liquid chromatography mobile phase for protein and peptide separation due to its properties like chromatographic selectivity, high volatility and low ultraviolet light cut-off.
Trifluoroacetic acid may be used as an analytical reference standard for the determination of the analyte in water matrices using high-performance liquid chromatography coupled to tandem mass spectrometry.
