FAQ

What is Sodium tungstate dihydrate (CAS: 10213-10-2)?

Sodium tungstate dihydrate (CAS: 10213-10-2) is a white crystalline inorganic compound with the chemical formula Na2WO4·2H2O. It is a hydrated form of sodium tungstate, commonly used as a source of tungsten in various industrial and research applications. The compound is soluble in water and exhibits mild hygroscopic properties, making it suitable for applications requiring controlled release of tungsten ions.

What are the main uses of Sodium tungstate dihydrate (CAS: 10213-10-2)?

Sodium tungstate dihydrate (CAS: 10213-10-2) is primarily used in the production of tungsten compounds, as a catalyst in chemical reactions, and in analytical chemistry for tungsten detection. It also finds applications in pharmaceuticals as an anticoagulant and in the manufacturing of certain specialty chemicals. Its unique properties make it valuable in research and industrial processes involving tungsten-based materials.

Is Sodium tungstate dihydrate (CAS: 10213-10-2) safe?

Sodium tungstate dihydrate (CAS: 10213-10-2) is generally considered low in toxicity, but it may cause mild irritation to skin and eyes. Safety data sheets (SDS) recommend handling with gloves and proper ventilation. While it is not classified as a hazardous substance under standard regulations, care should be taken to avoid prolonged exposure and follow standard chemical safety protocols.

How should Sodium tungstate dihydrate (CAS: 10213-10-2) be stored?

Sodium tungstate dihydrate (CAS: 10213-10-2) should be stored in a cool, dry place, away from moisture and light. Maintain storage temperature below 25°C (77°F) and humidity levels under 60% to ensure stability. Keep in airtight containers to prevent hygroscopic degradation and avoid contact with incompatible materials like strong acids or reducing agents.
