Sodium Trimetaphosphate(CAS: 7785-84-4)

Sodium trimetaphosphate (CAS 7785-84-4) is a sodium salt of trimetaphosphoric acid with the chemical formula Na3P3O9. It is a white, water-soluble powder known for its chelating properties and ability to prevent scaling in industrial applications. Sodium trimetaphosphate is commonly used in water treatment and pharmaceuticals due to its chemical stability and reactivity with metal ions.

Sodium trimetaphosphate (CAS 7785-84-4) is widely used in pharmaceuticals as a metal chelator, in the food industry as an emulsifier and stabilizer, and in industrial water treatment for corrosion inhibition. It also serves as a flame retardant additive and is employed in research for pH regulation and analytical chemistry applications. Its versatility makes it valuable in multiple sectors, including detergents and polymer processing.

Sodium trimetaphosphate (CAS 7785-84-4) is generally considered non-toxic and safe for use under proper handling conditions. However, it may cause mild irritation if inhaled or contacted with skin/eyes, so protective measures like gloves and ventilation are recommended. Safety standards classify it as low hazard, but occupational exposure should be minimized to ensure compliance with chemical safety guidelines.

Sodium trimetaphosphate (CAS 7785-84-4) should be stored in a cool, dry place, away from moisture and light. Keep in airtight, sealed containers to prevent hygroscopic degradation. Storage conditions should maintain temperatures below 25°C and humidity levels below 60% to preserve stability. Avoid exposure to water and ensure proper labeling for safe handling and storage.
