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.

Grade Specifications
Maximum level of impurities: Insoluble matter 0.0005%, Residue after ignition 0.01%, pH of a 5% solution 6.7-7.3 at 25?, Cl 5ppm, NO₃ 0.001%, SO₄ 0.001%, Heavy Metals (as Pb) 5ppm, Fe 5ppm

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