Product Application of Potassium Phosphate Dibasic CAS#7758-11-4
Potassium phosphate dibasic is a versatile chemical with wide-ranging industrial and laboratory applications. It is used as a corrosion inhibitor in antifreeze and as a nutrient in antibiotic culture media. In the fermentation and pharmaceutical industries, it acts as a phosphorus and potassium regulator, bacterial culture medium, and raw material for producing potassium pyrophosphate.
In the food industry, it serves as a buffer, flavoring and bulking agent, mild alkaline agent for dairy products, fermentation aid, and raw material for alkaline water in pasta production. It also improves product quality by regulating pH, ionic strength, and metal ion interactions, enhancing water retention and bonding in foods.
Additional applications include feed additives for nutritional supplementation, water and boiler treatment, analytical reagent, chelating agent, and microorganism or fungus culture agent. Potassium phosphate dibasic is also used as a liquid fertilizer and corrosion inhibitor in ethylene glycol antifreeze.
