Descrizione

Descrizione generale

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.

Applicazioni

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).

for use as solvent for perchloric acid titration

Confezionamento
