Descrizione

Application

Sodium phosphate tribasic dodecahydrate was used to prepare buffer solution used in the analysis of pyronaridine in human whole blood and plasma by using high-performance liquid chromatography.[1]

Biochem/physiol Actions

Sodium phosphate tribasic also referred to as Trisodium phosphate or TSP is a widely used cleaning agent. Trisodium phosphate disrupts cytoplasmic as well as outer membranes of Salmonella enterica cells and hence prevents the spread of bacteria.[2] Further, it is corrosion inhibitor for iron and inhibits the rate of the anodic iron dissolution reaction in unbuffered solutions.
