  • Applications

    Disodium oxoglurate (CAS 305-72-6) is used primarily as an intermediate in chemical synthesis and as a chelating, stabilizing, and pH-adjusting agent in industrial formulations; it also serves as a nutrient source and fermentation substrate for microbes in industrial biotechnology and as a precursor to amino acids and other nitrogen-containing compounds. In cosmetics and personal care, it can act as a buffering and stabilizing agent in formulations; in coatings, inks, and cleaning products, it may function as a metal-chelating additive to improve stability and performance; in polymers and plastics it can serve as a processing aid and stabilizer. Applications vary with local regulations and formulation limits.
