Chemical Properties

white crystals

Uses

Sodium Pyrophosphate Decahydrate is a tetrabasic pyrophosphate salt used in buffers.

Uses

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

Uses

Sodium pyrophosphate decahydrate is used in fusion matrix.

Definition

ChEBI: Sodium pyrophosphate decahydrate is a hydrate that is the decahydrate form of sodium diphosphate. It has a role as a food thickening agent, a food emulsifier and a chelator. It contains a sodium diphosphate.

General Description

Sodium pyrophosphate tetrabasic decahydrate functions as a sequestering, clarifying, buffering agent and water softener. It is used as an emulsifier, pH buffer and dough conditioner. Sodium pyrophosphate tetrabasic acts as a thickening agent in puddings and tartar control agent in toothpaste.

Purification Methods

Crystallise the salt from hot H2O and dry it in air at room temperature.
