Applications

Ammonium acetate is a reagent used in chromatographic analysis of various compounds such as oligos, proteins, and peptides. It is also employed with acetic acid to provide a buffer solution. Generally it behaves as a catalyst in many reactions like Knoevenagel, Borch. It is also employed as a nutrient additive.

Notes

Ammonium acetate is stable but deliquescent and it tends to lose ammonia. Decomposes in hot water. It is hygroscopic in nature.
