Sodium pyrophosphate decahydrate #CAS13472-36-1
Anhydrous sodium pyrophosphate is a white crystalline powder that readily absorbs moisture from the air and deliquesces. Sodium pyrophosphate decahydrate is a colorless monoclinic crystal or white crystalline powder that readily effloresces in dry air. It loses its water of crystallization when heated to 100°C. It is readily soluble in water, and its aqueous solution is alkaline; it is insoluble in alcohol. Its aqueous solution is stable below 70°C, but hydrolyzes to disodium hydrogen phosphate upon boiling. It has a strong pH buffering capacity and a certain chelating effect on metal ions.
Application of Sodium pyrophosphate decahydrate
Sodium pyrophosphate decahydrate is used in fusion matrix.Sodium Pyrophosphate Decahydrate is a tetrabasic pyrophosphate salt used in buffers.
Sodium pyrophosphate tetrabasic decahydrate has been used:
for pyrophosphate hydrolysis and quantification
as a component of extraction buffer to homogenize liver
as a component of cell lysis buffer for western blotting
