Potassium phosphate monobasic by MP Biomedicals is a high grade reagent. This compound is an inorganic salt of potassium and the dihydrogen phosphate ion. It is available as a white crystalline powder which is soluble in water, slightly soluble to insoluble in ethanol and insoluble in alcohol. It has a melting point of 252.6 C and decomposes above 400 C. Potassium phosphate is a reagent with high buffering capacity. It is manufactured by the action of phosphoric acid on potassium carbonate. CAS No. 7778-77-0 Quantity Provided: 500 gm per pack Molecular Formula: KH2PO4 Molecular Weight: 136.08 Soluble in water Potassium phosphate is widely used in chemical and biological sectors. It is generally incorporated in fertilizer blends as a nutrient source, for greenhouse trade and in hydroponics. It is widely used as a component for a wide variety of media used in the culture of microorganisms, as a component in phosphate buffered saline (PBS). In addition to helping maintain pH, it supplies essential phosphate required for growth of organisms. As a crystal it is used in optical modulators and for non-linear optics such as second-harmonic generation (SHG). These reagents may be used in the synthesis of various compounds in industrial processes, and are suitable for research.
