Disodium hydrogen phosphate heptahydrate

Description:

Disodium hydrogen phosphate heptahydrate, with the CAS number 7782-85-6, is an inorganic compound characterized by its chemical formula Na2HPO4·7H2O. This substance appears as a white crystalline solid and is highly soluble in water, making it useful in various applications. It is commonly utilized as a buffering agent in biochemical and molecular biology laboratories, helping to maintain stable pH levels in solutions. The heptahydrate form indicates that it contains seven water molecules per formula unit, which contributes to its hygroscopic nature, allowing it to absorb moisture from the environment. Disodium hydrogen phosphate is also employed in food processing as an emulsifier and in the preparation of certain types of fertilizers. Additionally, it plays a role in the synthesis of other phosphate compounds. Its properties include being non-toxic and relatively stable under standard conditions, although it should be handled with care to avoid inhalation or ingestion.
