Description and Uses
Sodium dihydrogen phosphate dihydrate acts as buffering capacity reagent in molecular biology, biochemistry and chromatography. It is used in the preparation of biological buffers. It is also used in the purification of antibodies, as a laxative and, in combination with other sodium phosphates.
Sodium phosphate monobasic dihydrate 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.
Recommended chemicals for the preparation of phosphate buffers are sodium dihydrogen phosphate dihydrate，NaH2PO4.2H2O(mol. wt.156.0)，disodium hydrogen phosphate dihydrate，Na2HPO4.2H2O (mol. wt.178.0), and sodium hydroxide pellets.
