Product Introduction:

Trifluoroacetic anhydride (TFAA) is a colorless and transparent liquid with a pungent odor, volatile, and the molecular formula is C4F6O3.

Trifluoroacetic Anhydride is a colorless volatile liquid in general state, hygroscopic, decomposed in water and ethanol, soluble in ether and acetic acid.

Trifluoroacetic anhydride is a representative strong dehydrating agent with a wide range of chemical reactivity.

It is usually refluxed with phosphorus pentoxide and purified by distillation before use.

Because there are two strong electron-withdrawing groups, trifluoromethyl, in its structure, it is a relatively strong organic acid anhydride, and its chemical properties are relatively active. Therefore, trifluoroacetic anhydride has a great use in organic synthesis.

Product Usage:

Trifluoroacetic anhydride is a commonly used reagent in chemical laboratories and is often used as an analytical reagent, solvent, catalyst, dehydration condensing agent, and protective agent for carboxyl and amino trifluoroacetylation.

Trifluoroacetic Anhydride is a raw material for preparing organic fluorine fine chemicals, medicines, pesticides, and new liquid crystal materials.

It is used as solvent, catalyst, dehydration condensing agent and retaining agent in the synthesis of various polymers and fine chemicals.

It is also widely used in dyes, photosensitive materials, liquid crystal display materials, aerospace technology, pesticides, medicine, polymer materials, etc.

Trifluoroacetic anhydride can react with carboxylic acid to form the corresponding mixed acid anhydride (i.e. activated ester), which enhances the electrophilicity of the carbonyl group of the carboxylic acid and makes it more difficult to be attacked by nucleophiles.

In the presence of a weak base, trifluoroacetic anhydride can be used as a dehydrating agent to dehydrate amides, oximes, hydroxy ketones or hydroxy acid esters to generate corresponding nitriles, unsaturated ketones or carboxylic acid esters.

The trifluoroacetyldimethylsulfonium salt of trifluoroacetic acid is a kind of very effective oxidant, which can oxidize alcohol to the corresponding carbonyl compound in high yield, and the oxidizing reagent is also relatively stable to halogenated hydrocarbons, which has many advantages.

It can improve the speed of the polymerization reaction and the yield of the product, and can be used as a derivatized chemical reagent in the detection of toxic metabolites and mycotoxins in livestock meat, fruits and vegetables by gas chromatography and high performance liquid chromatography, and has a very good development and application prospect.
