Product Description

Product Description of Potassium Phosphate Dibasic CAS#7758-11-4

Dipotassium phosphate is a multifunctional source of phosphorus and potassium, mainly used as a fertilizer. It is also widely applied in food industry as a food additive and electrolyte ingredient in fitness supplements. In pharmaceutical fields, it acts as a diuretic and laxative. It can prevent coagulation in artificial dairy creamers and be added to beverage powders. Moreover, it is commonly used in labs to prepare buffer solutions and trypticase soy agar for bacterial culture plates.


Product Application of Potassium Phosphate Dibasic CAS#7758-11-4

Dipotassium phosphate is a multifunctional chemical for extensive industrial and laboratory uses. It works as a corrosion inhibitor in antifreeze and a nutrient in antibiotic culture media. In fermentation and pharmaceutical industries, it acts as a phosphorus and potassium regulator, bacterial culture medium, and raw material for potassium pyrophosphate. In food industry, it functions as a buffer, flavor enhancer, bulking agent and mild alkaline agent for dairy products. It also serves as a fermentation aid and raw material for alkaline water in pasta making. It optimizes food quality by adjusting pH value and ionic strength, chelating metal ions, and improving water retention and cohesion. It is also applied as feed additive, water and boiler treatment agent, analytical reagent, chelating agent, and microbial culture agent. Additionally, it can be used as liquid fertilizer and corrosion inhibitor in ethylene glycol antifreeze.
