Product Details

Potassium Phosphate Monobasic #CAS7778-77-0

Potassium dihydrogen phosphate is a kind of highly efficient and rapid dissolving phosphorus and potassium compound fertilizer containing, phosphorus and potassium, two elements for providing the necessary nutrients for plant growth and development, being applicable to any soil and crop, especially being applicable to the treatment of regions of simultaneous lack of phosphorus and potassium nutrients and phosphorus-preferred and potassium-preferred crops. It is mostly used for root top dressing, seed soaking, and seed dressing, being able to yield significant effect. If it sued for the roots fertilization, it can be used as basal fertilizer, seed fertilizer or moderate-late phase topdressing.
Its aqueous solution can react with silver nitrate, generating yellow phosphorus dihydrogen phosphate precipitation, being able to be used as a differential reaction.

Application of Potassium Phosphate Monobasic

(1) As feed phosphorus additives; In the food industry, it is used for the manufacture of baked goods, for leavening agent, flavoring agent, fermentation additives, nutritional fortifiers, yeast food. Also used as a buffer, chelating agent.
(2) It can be used as fertilizer, flavoring agent and the culture agent of brewing yeast; used for the preparation of buffer solution, also used in medicine and manufacturing of potassium metaphosphate.
(3) It can be used for the fertilization of rice, wheat, cotton, rape, tobacco, sugar cane, apple and other crops.
(4) It can be used as chromatography reagents and buffer, but also for the synthesis of medicine.
As a highly efficient fertilizer, it is suitable for all kinds of soil and crops. It can also used as a bacterial culture agent, the flavoring agent for the synthesis of sake and the raw material for making potassium metaphosphate. In medicine, it is used for the uric acidification as a nutritional agent.
(5) Used as feed nutritional supplements;As a quality improver, it has effects of improving the complexation metal ions and pH value, increasing the ionic strength of food, and thus improving the adhesion and water holding capacity of food. China provides that it can be used for wheat flour with the maximum usage amount of 5.0g/kg and 2.0 g/kg in the beverage.

 Monopotassium phosphate (MKP) is a specialty fertilizer that is a good source of phosphorus and potassium.It is an acid, chloride-free, dry soluble fertilizer,and is a natural pH buffer with a buffer pH in pure water of 4.5.Monopotassium phosphate can be solubilized and blended with liquid fertilizers that will not salt out at a low pH, and is also safe to use as a foliar fertilizer.

potassium phosphate is a humectant and pH adjuster used in cosmetic formulations. Potassium phosphate is an inorganic salt.

In buffers for determination of pH. Pharmaceutic aid (buffering agent).

Potassium Dihydrogen is a buffer, neutralizing agent, and sequestrant. It is mildly acid, with a ph of 4.5, and fairly soluble in water, with a solubility of 25 g in 100 ml at 25°c. It is used in whole eggs for color preservation and is also used in low-sodium products, milk products, and meat products. Typical usage ranges from 0.1 to 0.5%. It is also termed monopotassium phosphate or thophosphate, potassium phosphate monobasic, and monopotassium monophosphate.
