General description

Acetic acid is an organic acid mainly used as a acidulating agent and flavoring agent. It is one of the main volatile constituents of vinegar and pyroligneous acid. Acetic acid is used as a flavoring agent in ice-creams, nonalcoholic beverages and baked goods. It is also used as a chemical reagent for the synthesis of vinyl acetate monomer, cellulose acetate, acetic anhydride, acetate ester, and terephthalic acid.

Application

Acetic acid can be used as a mobile phase additive to improve the separation and resolution of the bioactive compounds on the C18 column in reverse phase HPLC. It is also used as an analytical reference standard in chromatographic applications.
