Ammonium acetate is a salt that can be used as a buffer. Ammonium acetate is commonly used as an additive for regulating the acidity of various foodstuffs and as a catalyst for Henry reactions. The compound is also used in agriculture, where it functions as a fungicide and insecticide. In biochemical research, ammonium acetate is used for precipitation of DNA and RNA. It is especially useful for precipitating RNA from dilute solutions and has been shown to produce less detergent precipitation than sodium chloride salt. Likewise, ammonium acetate can be used to facilitate precipitation in the extraction of proteins, particularly from tissues not naturally rich in them.
