Disodium succinate is widely used in the pharmaceutical and food industries as a buffering agent and stabilizer. It helps maintain pH balance in formulations, making it valuable in injectable medications and oral solutions where stable pH is critical for drug efficacy. In food production, it acts as an acidity regulator, enhancing flavor stability and shelf life of processed foods. It is also used in cell culture media and biochemical research as a metabolic intermediate, supporting studies related to the Krebs cycle. Due to its solubility and biocompatibility, it serves as an excipient in various diagnostic and therapeutic products.
