Used as a volatile buffer in HPLC and mass spectrometry in organic synthesis for amidepeptide production as a reagent in dyes antibiotics pesticides and food additives like vinegar substitutes.

Acts as a mild acid-base salt for pH buffering in analytical chemistry and protein precipitation thermally decomposes cleanly to avoid residue in reactions requiring ammonia or acetate sources.

Ammonium acetate is a white deliquescent crystalline solid with a slight acetic odor molecular weight of 77.08 gmol density of 1.17 gcm and melting point around 114C where it often decomposes.
