di-Sodium hydrogen phosphate

Sodium dibasic anhydrous is used as a sequestrant, emulsifier and buffer in foods, as mordant in dyeing for weighting silk, in tanning, in manufacturing of enamels, ceramics, detergents, boiler compounds; as fireproofing agent in soldering and brazing instead of borax; as reagent and buffer in analytical chemistry, cathartic.,laxative.


It a reagent with very high buffering capacity widely used in molecular biology, biochemistry and chromatography. Useful in conjunction with Sodium Phosphate, Monobasic in the preparation of biological buffers. Used in many applications including the purification of antibodies.


Soluble in water, but more soluble in hot water; insoluble in alcohol, ethanol.
