Sodium phosphate dibasic heptahydrate is a reagent with very high buffering capacity widely used in molecular biology, biochemistry and chromatography. Sodium phosphate dibasic is highly hygroscopic and water soluble. Useful in conjunction with Sodium Phosphate, Monobasic in the preparation of biological buffers.
Sodium phosphate dibasic is highly hygroscopic and water soluble. Useful in conjunction with Sodium Phosphate, Monobasic in the preparation of biological buffers.
Sodium phosphate dibasic heptahydrate is use in many applications such as sequestrant, emulsifier and buffer in foods. As mordant in dyeing for weighting silk, in tanning. In manufacturing of enamels, ceramics, detergents; as fireproofing agent in soldering and brazing instead of borax; as reagent and buffer in analytical chemistry, cathartic, laxative.
Soluble in water, but more soluble in hot water; insoluble in alcohol, ethanol.
