Sodium selenate decahydrate is the fully hydrated, crystalline form of the inorganic selenium salt Na2SeO4·10H2O. It is produced through the controlled oxidation of selenium dioxide or elemental selenium in the presence of sodium hydroxide, followed by crystallization to yield a high-purity, free-flowing solid. The decahydrate form is the most common commercial grade, offering excellent water solubility and consistent selenium content for precise formulation.
As a source of hexavalent selenium, this compound plays a critical role in both pharmaceutical and nutritional applications. It is widely used in total parenteral nutrition (TPN) solutions, as a selenium supplement in animal feed and human nutraceuticals, and as a reagent in biochemical research. Its high solubility and stability make it a preferred choice for liquid formulations where accurate dosing of selenium is essential.
