Sodium selenite pentahydrate

Synonyms: Sodium selenite pentahydrate, Disodium selenite pentahydrate, Selenious acid disodium salt pentahydrate, Sodium selenium oxide pentahydrate, Na2SeO3·5H2O

Sodium selenite pentahydrate is the hydrated, inorganic form of sodium selenite, a selenium(IV) salt that appears as white, water-soluble crystals. It is manufactured by reacting selenium dioxide with sodium hydroxide under controlled conditions, followed by crystallization to yield the pentahydrate. The material is supplied as a high-purity grade suitable for pharmaceutical, nutraceutical and veterinary applications.

As a highly bioavailable source of selenium, it serves as a critical trace element in total parenteral nutrition (TPN) formulations, dietary supplements, and animal feed premixes. Its well-defined stoichiometry and rapid dissolution profile make it a preferred choice for formulators who require precise selenium dosing and consistent analytical behavior.
