??

Sodium tungstate dihydrate is currently being investigated as a potential therapy for obesity. Sodium tungstate dihydrate is also an inhibitor of acid phosphatases.

??

ChEBI: A hydrate that is the dihydrate form of sodium tungstate. Combines with hydrogen peroxide for the oxidation of secondary amines to nitrones

?? ??

Sodium tungstate dihydrate is a sodium salt of tungstic acid, which occurs as white colorless crystals.

Purification Methods

The salt crystallises from hot water (0.8mL/g) on cooling to 0o. [Grüttner & Jender in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol II p 1727 1965].
