Use

Trifluoroacetic acid is mainly for the production of new pesticide, medicine and dyes, and also has great potential of application and development in the fields of materials and solvents. trifluoroacetic acid is mainly used for the synthesis of various kinds of trifluoromethyl group or heterocyclic containing herbicides. it is currently available for synthesizing various kinds of novel herbicide containing pyridyl and qunoilyl; acting as a strong proton acid, it is widely applied as the catalyst for alkylation, acylation, and olefin polymerization of aromatic compound; as a solvent, trifluoroacetic acid is a kind of excellent solvent for fluorination, nitration and halogenations. in particular, the excellent protective effect of its trifluoroacetyl derivatives on hydroxy and amino group has very important application in the synthesis of amino acid and poly-peptide synthesis.
