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. Specification Item Specification Vapor pressure 0Pa at 20℃ Density 1.40 g/mL at 20 °C SOLUBLE Soluble in water pKa (1) 2.15, (2) 6.82, (3) 12.38 (at 25℃) PH 4.0 – 4.5 (25℃, 50g/L in water) λmax λ: 260 nm Amax: ≤0.025λ: 280 nm Amax: ≤0.02 Application Sodium phosphate monobasic has a wide range of applications and can be used as a raw material for the production of sodium hexametaphosphate and sodium pyrophosphate; It can also be used for leather making and boiler water treatment; As a quality improver and baking powder, it is used as a buffering agent and fermentation powder raw material in the food and fermentation industries; It is also used as a feed additive, detergent, and dyeing assistant Packing Usually packed in 25kg/drum,and also can be do customized package.
