Disodium succinate solution is widely used in pharmaceutical, biochemical, and food applications. In the food industry, it acts as a pH adjuster and stabilizer, particularly in canned foods and sauces, helping to maintain product stability. It serves as a buffering agent in injectable medications, helping to maintain stable pH levels during storage and delivery. Due to its role in the Krebs cycle, it is used in energy metabolism studies and in the formulation of parenteral nutrition solutions to support cellular energy production. It is also employed in cell culture media to support the growth of certain microorganisms and mammalian cells by acting as a carbon source. In analytical chemistry, it functions as a mobile phase additive in HPLC for the separation of organic compounds. Additionally, it finds use in cosmetic formulations as a pH adjuster and skin conditioning agent.
