Description and Uses

Potassium Phosphate Dibasic is a common source of phosphorus and potassium, which is often used as a fertilizer. It is also widely applied in the food industry, such as food additive and electrolyte replenisher for workout supplement. Another usage of Potassium Phosphate Dibasic is as a medicine, who serves as a diuretic or laxative. Besides, it is employed in the production of imitation dairy creamers to prevent coagulation and used in certain powders to prepare beverages. In addition, it is commonly seen in chemical laboratories for producing buffer solutions and trypticase soy agar which is used to make agar plates for culturing bacteria.

Buffering agent in antifreeze solutions; nutrient in the culturing of antibiotics; ingredient of instant fertilizers; as sequestrant in the preparation of non-dairy powdered coffee creams.
