Potassium Phosphate Tribasic CAS 7778-53-2 Assay >98.0% (Titration)

Potassium Phosphate Tribasic (CAS: 7778-53-2) is a reagent with a very high buffering capacity. It is widely used in molecular biology, biochemistry, and chromatography. It is used as a food additive for its properties as an emulsifier, foaming agent, and whipping agent.
It serves as a buffering agent to regulate pH, Typically used as a component for a wide variety of media used in the culture of microorganisms, as a component in phosphate buffered saline (PBS). It occurs in several forms: monobasic, dibasic, and tribasic (K3PO4). Most pH neutral potassium phosphate buffer solutions consist of mixtures of the monobasic and dibasic forms to varying degrees, depending on the desired pH. Gomori buffers, the most commonly used phosphate buffers, consist of a mixture of monobasic dihydrogen phosphate and dibasic monohydrogen phosphate. By varying the amount of each salt, a range of buffers can be prepared that buffer well between pH 5.8 and pH 8.0 (please see the tables below). Phosphates have a very high buffering capacity and are highly soluble in water.
Potassium phosphate is an acidity regulator and chelating agent (used to bind metal ions). It prevents desiccation and is used as an acid stabiliser in powders as well as to prevent formation of clumps. It increases the activity of antioxidants.
In the food industry (Food additives), it is used as emulsifier, potassium fortifier, flavoring agent, meat binder. Potassium phosphate helps stabilize, thicken and regulate the acidity and moisture in foods.
Also used in medicine. Potassium phosphate is sometimes used as a medicine. It can have a diuretic effect and act as a laxative when used in medicinal amounts.
Potassium Phosphate Tribasic can be used as analytical reagent, buffer and softener.
