Potassium Citrate (CAS 6100-05-6) is a tribasic citrate salt derived from citric acid fermentation and supplied as a white crystalline granular powder; it serves food and pharmaceutical formulators as a buffering and alkalizing agent for carbonated beverages, electrolyte balancing and urological medications. Derived from citric acid fermentation, it offers a mild saline taste and is used for electrolyte balancing in neutral pH environments.
