Disodium succinate is widely used in the pharmaceutical and food industries as a buffering agent and stabilizer. It helps maintain a stable pH in formulations, making it valuable in injectable medications and oral solutions. In food production, it acts as an acidity regulator, enhancing flavor stability and shelf life. It is also used in cell culture media and biochemical research as a metabolic intermediate, supporting studies related to the citric acid cycle. Additionally, disodium succinate finds application in dermatological products for its skin-conditioning properties, helping to improve hydration and barrier function.
