Cas no 18996-35-5 (Sodium Dihydrogen Citrate)
Sodium Dihydrogen Citrate is a water-soluble salt derived from citric acid, commonly used as a buffering agent, chelator, and acidity regulator in pharmaceutical, food, and industrial applications. Its key advantages include precise pH control in formulations, excellent biocompatibility, and the ability to sequester metal ions, enhancing stability in solutions. The compound exhibits mild acidity, making it suitable for sensitive applications where aggressive acids are undesirable. It is also valued for its low toxicity and biodegradability, aligning with environmental and safety standards. Its multifunctional properties make it a versatile choice in medical infusions, food preservation, and detergent formulations.
