We Wuhan Ruisunny Chemical Co., Ltd has been focusing on trading of such chemicals as Calcium Hypochlorite, Trichloroisocyanuric Acid, Ammonium Bicarbonate, Sodium Hydroxide, Hydrogen Peroxide and Silane etc. since 2007. We hereby have following details for the product as:
Potassium phosphate dibasic is a useful biological buffer having a pH in the range of 8.5-9.6. Potassium phosphate is present in various forms: monobasic (KH2PO4), dibasic (KH2PO4), and tribasic (K3PO4). Potassium phosphate buffers are widely employed in equilibrium dialysis, high performance liquid chromatography (HPLC) and affinity capillary electrophoresis studies.

4) Application:
Dipotassium hydrogen phosphate can be used as corrosion inhibitor of antifreeze, nutrient of antibiotic culture medium, phosphorus and potassium regulator of fermentation industry, feed additive, medicine, fermentation, bacterial culture and preparation of potassium pyrophosphate, as feed phosphorus supplement additive. Potassium hydrogen phosphate can also be used as water treatment agent, microorganism, fungus culture agent and other purposes. It is often used as analytical reagent and buffer. It is also used in pharmaceutical industry. In food industry, it is used as raw material for preparing alkaline water for pasta products, fermentation agent, flavoring agent, bulking agent, mild alkaline agent for dairy products and yeast food. Dipotassium hydrogen phosphate can be used as buffer, chelating agent and analytical reagent. Buffers and pharmaceuticals. Dipotassium hydrogen phosphate can be used for boiler water treatment. In medicine and fermentation industry, dipotassium hydrogen phosphate can be used as phosphorus and potassium regulator and bacterial culture medium. It is the raw material for producing potassium pyrophosphate. It can be used as liquid fertilizer and corrosion inhibitor of ethylene glycol antifreeze. Feed grade is used as feed nutritional supplement. Potassium dihydrogen phosphate can be used as a product quality improver, which can improve the complex metal ions, pH value and ionic strength of food, so as to improve the bonding force and water holding capacity of food. China stipulates that dipotassium hydrogen phosphate can be used for fat planting powder, with a maximum dosage of 19.9g/kg.
