| Application: | Acetic acid is widely employed as solvent for various oxidation reactions. It 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). |
| General description: | Acetic acid is an organic carboxylic acid. It is a hygroscopic liquid having 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. |
| Other Notes: | The article number 27221-6X1L will be discontinued. Please order the single bottle 27221-1L which is physically identical with the same exact specifications. |
