| Application: | Acetic acid has been 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). |
| Application: | for use as solvent for perchloric acid titration |
| General description: | Acetic acid is an organic carboxylic acid. It is a hygroscopic liquid having a pungent odor. Its anhydrous form is commonly referred as glacial acetic acid. It forms dimers linked by hydrogen bonds in solution and gaseous phases. It is weakly acidic in nature. |
