  • Applications

    Potassium Succinate (CAS 676-47-1) is used as a nutrient source for microorganisms and as a buffer in fermentation and biopharmaceutical processing; it serves as a pH stabilizer and component in a range of industrial formulations; it acts as a chelating agent to sequester metal ions in cleaning solutions, coatings, and metal-processing chemistries; it functions as an intermediate or building block for organic synthesis and succinate-based polymers; it may be considered as a buffering or nutrient additive in certain food processing applications related to fermentation.
