CAS 7558-79-4 Food Grade Na2HPO4 Disodium Hydrophosphate Disodium / Sodium Phosphate

CAS 7558-79-4 Food Grade Na2HPO4 Disodium Hydrophosphate Disodium Phosphate Sodium Phosphate, Dibasic

Disodium phosphate, also known as sodium phosphate dibasic or disodium hydrogen phosphate, is an inorganic compound with the chemical formula Na2HPO4. It is a white, crystalline powder that is highly soluble in water.  

Description:
Disodium phosphate is a sodium salt of phosphoric acid. It is composed of two sodium ions (Na+) and one phosphate ion (HPO42-). It is typically available in both hydrated and anhydrous forms. The hydrated form may contain varying amounts of water molecules.

Technical Data:

• Chemical Formula: Na2HPO4 (anhydrous), Na2HPO4.xH2O (hydrated)
• Molecular Weight: 141.96 g/mol (anhydrous)
• Melting Point: Anhydrous disodium phosphate melts at approximately 250°C (482°F).
• Solubility: Disodium phosphate is highly soluble in water, with solubility varying depending on the hydrated or anhydrous form.

Features:

1. pH Buffering: Disodium phosphate is commonly used as a pH buffering agent due to its ability to maintain a stable pH in solutions.
2. Water Softening: It is used in water treatment applications to help reduce water hardness by sequestering calcium and magnesium ions.
3. Emulsification and Stabilization: Disodium phosphate can act as an emulsifier and stabilizer in food and beverage products, helping to improve texture and prevent ingredient separation.
4. Nutrient Supplement: It is used as a source of phosphorus and sodium in some nutrient formulations, animal feeds, and fertilizers.
5. Cleaning Agent: Disodium phosphate is employed in cleaning products, especially in commercial and industrial settings, as a pH adjuster and detergent builder.
