General description

Acetic acid is an organic carboxylic acid. It is a pungent smelling hygroscopic liquid. Glacial acetic acid is the anhydrous acetic acid. It forms dimers linked by hydrogen bonds in solution and gaseous commonly referred as phases. It is weakly acidic in nature.

Application

Acetic acid is widely employed as solvent for various oxidation reactions. It may be used in the analysis of synthetic peptides by electron transfer dissociation (ETD) tandem mass spectrometry (MS/MS). It may be used in the preparation of peroxyacetic acid (disinfectant), via reaction with perhydrol (30% hydrogen peroxide).
