Application
NH4C2H3O2 is occasionally employed as a biodegradable de-icing agent.
It is often used with acetic acid to create a buffer solution, one that can be thermally decomposed to non-ionic products
Ammonium acetate is useful as a catalyst in the Knoevenagel condensation and as a source of ammonia in the Borch reaction in organic synthesis.
It is a relatively unusual example of a salt that melts at low temperatures.
Can be used with distilled water to make a protein precipitating reagent.
Is often used as an aqueous buffer for ESI mass spectrometry of proteins and other molecules.
Useful in dialysis as part of a protein purification step to remove contaminants via diffusion.
Ammonium acetate is volatile at low pressures. Because of this, it has been used to replace cell buffers with non-volatile salts in preparing samples for mass spectrometry. It is also popular as a buffer for mobile phases for HPLC with ELSD detection for this reason. Other volatile salts that have been used for this include ammonium formate.
