Description

CAS: 7778-53-2 | K3O4P | 212.265 g/mol

Potassium phosphate tribasic is a reagent with a very high buffering capacity. It is widely used in molecular biology, biochemistry, and chromatography, used for the extraction of keratohyalin protein from bovine tissue, to study the effects of freezing and thawing on the stability of proteins sensitive to conformational changes. It is used as a food additive for its properties as an emulsifier, foaming agent, and whipping agent.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
