Acetic anhydride

Descrição detalhada : Acylation, an alternative to silylation, enables the conversion of compounds that comprise of active hydrogens (-OH, -SH and -NH) into esters, thioesters, and amides by the action of a carboxylic acid or derivative. The carbonyl group adjacent to the halogenated carbons favors the improvement of electron capture detector (ECD) response. Acylation has several benefits:. It increases the stability of compounds by protecting unstable groups.. It may render volatility on substances like carbohydrates or amino acids, that have several polar groups that they are non-volatile and generally decompose on heating.. It allows the separations not possible with underivatized compounds.. Compounds are detectable at very low levels with an ECD.Acetic anhydride is a reagent utilized to form fragmentation-directing derivatives for GC/MS analysis., Acetic anhydride is an esterification agent which is corrosive to metals. It is a colourless liquid with strong vinegar-like odour. It is mostly used in making plastics, fibers, pharmaceuticals, dyes and explosives.
