What is Sodium phosphate monobasic CAS 7558-80-7?
Sodium phosphate monobasic is a colorless crystalline or white crystalline powder, odorless and easily soluble in water. Its aqueous solution is acidic and almost insoluble in ethanol. When heated, it loses its crystalline water and decomposes into acidic sodium pyrophosphate (Na3H2P2O7). Commonly used in the fermentation industry to regulate acidity and alkalinity, it is often used in conjunction with disodium hydrogen phosphate as a food quality improver in food processing. Such as improving the thermal stability of dairy products, making pH regulators and binders for fish products, etc.
