Monobasic sodium phosphate forms acidic aqueous solutions and is poorly soluble in ethanol. The source distinguishes anhydrous powder or granules from crystalline hydrated forms. Its application areas include buffering, analytical reagents, sequestration, emulsification and dye mordanting. Additional industrial uses extend to ceramics, enamels, detergents and boiler chemicals, with the required hydration state determined by the particular formulation.

product description

Available in multiple forms: white powder, granules, or colorless to white crystalline powder, providing flexibility for different applications.

Relatively soluble in water, making it easy to prepare aqueous solutions.

Slightly acidic aqueous solution (pH around 4.5), suitable for applications requiring mild acidity.

Insoluble in ethanol and only slightly soluble in chloroform, ensuring stability in non-aqueous solvents.


Product Description of Sodium phosphate monobasic CAS#7558-80-7

Anhydrous product is white powder or granules; dihydrate is colorless to white crystals or crystalline powder. Moderately soluble in water to form acidic solution at pH approx 4.5, practically insoluble in ethanol and slightly soluble in chloroform.


Product Application of Sodium phosphate monobasic CAS#7558-80-7

Monobasic sodium phosphate monohydrate is widely used as a sequestrant, emulsifier and dye mordant, as well as a reagent and buffer in food and analytical chemistry. It also acts as a fire retardant and silk weighting agent in tanning. Furthermore, it is applied in enamels, ceramics, detergents and boiler chemicals, and can replace borax in soldering and brazing.
