Verwenden
It is used as a buffering agent.
Verwenden
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.
Verwenden
Potassium phosphate tribasic has been used:
- in lysis buffer for the isolation of protein from Gram positive bacteria
- as a reagent for the scalable synthesis and post-modification of NU-1000 (mesoporous metal-organic framework)
- as a reagent for the plasma membrane preparation of Lilium davidii or Oryza sativa with high purity
Definition
ChEBI: Tripotassium phosphate is an inorganic potassium salt that is the tripotassium salt of phosphoric acid. It is an inorganic phosphate salt and an inorganic potassium salt.
synthetische
The tribasic salt is produced by complete neutralization of phosphoric acid with potassium hydroxide, followed by evaporation and crystallization:H₃PO₄+ 3KOH →K₃PO₄+ 3H₂O.
Allgemeine Beschreibung
Potassium phosphate tribasic exhibits high catalytic property in trans esterification reactions. It has bactericidal activity.
