Trifluoroacetic Acid (LCMS Grade TFA)
Description
Product Name: LCMS Grade TFA (Trifluoroacetic acid)Alternative Names: LCMS TFA; LCMS TFA Amps; TFA Ampules; Trifluoroacetic acid; TFA Acid; CAS# 76-05-1; Perfluoric acid; 2,2,2-Trifluoroacetic acid; HPLC TFA CovaChem's LCMS Grade Trifluoroacetic acid (TFA) is well suited as a chromatography additive for difficult to separate analytes in HPLC and LCMS applications. CovaChem's LCMS TFA is an ideal additive for separations of peptides in peptide synthesis applications. Trifluoroacetic acid is widely used to separate both protected amino acid chains and deprotected peptides. Due to the amino and carboxylate groups having vastly different pka values, synthetic peptides can be particularly challenging to separate, The HPLC separation of peptides is much more easily achieved with 0.1% Trifluoroacetic acid being present in the mobile phase.
