  Potassium citrate , with CAS number of 866-84-2, can be called 1,2,3-Propanetricarboxylic acid, 2-hydroxy-, tripotassium
salt ; Citric acid, tripotassium salt ; Potassium tribasic citrate ; Tripotassium citrate . Potassium citrate (CAS NO.866-84-2) is effective in reducing the pain and frequency of micturition when these are caused by highly acidic urine. It is used for this purpose in dogs and cats. It is an effective way to treat/manage gout and arrhythmia.In common with other substances that render the urine alkaline, it may be used to reduce the danger of crystalluria during sulfonamide therapy. It is widely used to treat urinary calculi (kidney stones), and is often used by patients with cystinuria. It is also used in many soft drinks as a buffering agent.
