Beschreibung

Allgemeine Beschreibung

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.[1]

Anwendung

Wird als Lösungsmittel für Titrationen mit Perchlorsäure verwendet.

Acetic acid has been used in the analysis of synthetic peptides by electron transfer dissociation (ETD) tandem mass spectrometry (MS/MS).[2] It may be used in the preparation of peroxyacetic acid (disinfectant), via reaction with perhydrol (30% hydrogen peroxide).[1]

Verpackung

Dieses Produkt ist auch in Glasflaschen erhältlich.
