INTRODUCTION
Ammonium acetate is a crystalline white solid with a somewhat acetous odour. It is also called the spirit of Mindererus in its aqueous form or Azanium acetate. It is widely used in chemical analysis, in preserving foods, and in pharmaceuticals. It is often used to prepare buffer solutions as it is made up of a weak base and a weak acid combined together.
Manufacture
Ammonium acetate is produced by the neutralization of acetic acid with ammonium carbonate or by saturating glacial acetic acid with ammonia.

Applications
| Ammonium acetate is commonly used as a controlling agent for food acidity. It alters or regulates the alkalinity or acidity of foods. |
| It is also commonly employed in the Knoevenagel condensation technique as a catalyst. The Borch reaction during organic synthesis uses the molecule as one of the greatest sources of ammonia. |
| A protein precipitating reagent is made by combining ammonium acetate with completely distilled water. |
| The substance may also be used as a buffer in ESI (electrospray ionization) mass spectrometry of molecules and proteins, as well as a mobile phase in HPLC (high-performance liquid chromatography). |
| It is used in the production of explosives. |
| It is used for making Foam rubber & Vinyl plastics. |
| In analytical chemistry, the compound is used in the form of a reagent. It is used as a reagent in different dialysis procedures for the elimination of contaminants through diffusion. |
| In agricultural chemistry, ammonium acetate, when used as a reagent, helps in determining soil CEC or cation exchange capacity along with the availability of potassium in the soil. |
