Sodium Selenite Pentahydrate Anhydrous BP Ph Eur Grade Manufacturers

CAS Number: pentahydrate: 26970-82-1 or (anhydrous: 10102-18-8), EINECS EC Number: 233-267-9, Molecular Formula: Na2SeO3-5H2O or (Na2O3Se), Molecular Weight: 263.01 or (172.95)

Sodium selenite is the inorganic compound with the formula Na2SeO3. This salt is a colourless solid. The pentahydrate Na2SeO3(H2O)5 is the most common water-soluble selenium compound. Sodium selenite is mainly used in the manufacture of colorless glass. The pink color imparted by these selenites cancels out the green color imparted by iron impurities. Sodium selenite is an ingredient in some food supplements.
