Ammonium succinate is widely used in the pharmaceutical industry as a buffering agent in various formulations, helping to maintain stable pH levels in medications. It also serves as a key intermediate in the synthesis of active pharmaceutical ingredients (APIs) and other organic compounds. In the food industry, it acts as a flavor enhancer and acidity regulator, improving the taste and shelf life of products. Additionally, it is utilized in biotechnology and microbiology as a nutrient source in culture media for the growth of microorganisms. In agriculture, it is applied as a foliar spray to promote plant growth and improve crop yield. Its chelating properties make it useful in water treatment processes for removing metal ions.
