Ode Chem LLP manufactures premium Di Sodium Phosphate (DSP) Heptahydrate. This hydrated form contains seven molecules of water of crystallization, providing a perfect balance of solubility and atmospheric stability. Unlike the 12H2O form which can melt in summer temperatures, the Heptahydrate remains a stable crystalline solid, making it ideal for consistent pharmaceutical and laboratory formulations.

Applications
Used as an analytical reagent in protein electrophoresis and as a primary standard in phosphate-related research.
Functions as a sequestrant and emulsifier in specialized dairy applications, particularly where a specific hydration state is required for solubility.
A critical component in the manufacturing of biologics and parenteral drugs where precise osmotic pressure and pH control are required.
Historically used in the preparation of specialized photographic developers and toning baths.
Serves as a raw material for the production of other specialty sodium salts.
Heptahydrate is more thermally stable and less likely to lose water (effloresce) or clump during storage in warm climates.
The specific CAS number is 7782-85-6.
36 months when stored in a cool, dry place away from moisture.
25 KG & 50 KG is out standard Pack size. Customization is available on requirement & request.
Our MOQ for Ammonium Chloride is 500 KG.
