FAQ

What is Sodium hydrogenphosphate dodecahydrate (CAS: 10039-32-4)?

Sodium hydrogenphosphate dodecahydrate (CAS: 10039-32-4) is a hydrated salt with the chemical formula NaHPO4·12H2O. It appears as a white crystalline powder, is highly soluble in water, and serves as a common phosphate-based compound used in various industrial and scientific applications. Its structure includes twelve water molecules per phosphate unit, contributing to its hygroscopic nature and stability in aqueous environments.

What are the main uses of Sodium hydrogenphosphate dodecahydrate (CAS: 10039-32-4)?

Sodium hydrogenphosphate dodecahydrate (CAS: 10039-32-4) is widely used as a buffering agent in pharmaceuticals and food products. In industry, it functions as a water softener and flame retardant. It also plays a role in research for pH regulation and in agriculture as a nutrient supplement. Its applications leverage its solubility, pH stability, and ability to chelate metal ions.

Is Sodium hydrogenphosphate dodecahydrate (CAS: 10039-32-4) safe?

Sodium hydrogenphosphate dodecahydrate (CAS: 10039-32-4) is generally considered safe when handled properly. It is non-toxic in typical exposure scenarios but may cause mild irritation to eyes and skin. Safety standards recommend following OSHA guidelines for handling, using protective gloves and goggles, and ensuring proper ventilation to avoid inhalation risks in industrial settings.

How should Sodium hydrogenphosphate dodecahydrate (CAS: 10039-32-4) be stored?

Sodium hydrogenphosphate dodecahydrate (CAS: 10039-32-4) should be stored in a cool, dry place (ideally below 25°C), away from moisture and light. Keep in a sealed, airtight container to maintain its hydration state and prevent degradation. Avoid exposure to humid environments to ensure long-term stability and efficacy.
