CAS 7782-82-3 — Sodium hydrogen selenite

Sodium hydrogen selenite (CAS 7782-82-3) is an inorganic selenium compound used primarily as a nutritional supplement in animal feed and as a reagent in biochemical research. It provides bioavailable selenium, an essential trace element for enzyme function and metabolic processes. This white crystalline solid has a molecular formula of HNaO3Se and a molecular weight of 150.96 g/mol. It must be stored at ambient temperatures under controlled conditions due to its hazardous nature, with a signal word of "Danger." Molekula supplies sodium hydrogen selenite from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
