Description

General description

Ammonium acetate is a colorless hygroscopic solid. It can be prepared by reacting glacial acetic acid with ammonia or ammonium carbonate. It has been reported as potential inhibitor of Pd/C mediated hydrogenolysis of benzyl ether.

Application

Ammonium acetate has been used in the mobile phase for the HPLC determination of ezetimibe and its metabolites. It may be used in preparation of phenanthrimidazoles and retinimidazoles.
