CAS 7775-14-6

Sodium dithionite

Description:

Sodium dithionite, with the chemical formula Na2S2O4 and CAS number 7775-14-6, is a white crystalline powder that is highly soluble in water. It is primarily used as a reducing agent in various chemical processes, including dyeing and bleaching in the textile industry, as well as in the production of certain chemicals. Sodium dithionite is known for its ability to donate electrons, which makes it effective in reducing metal ions and other compounds. It has a relatively low toxicity but can release sulfur dioxide when decomposed, which poses safety considerations. The substance is stable under dry conditions but can decompose in the presence of moisture or heat, leading to the formation of sulfur and other byproducts. Additionally, sodium dithionite is sensitive to air and should be stored in airtight containers to prevent oxidation. Its applications extend to the food industry, where it is sometimes used as a food additive, and in analytical chemistry for various reduction reactions.
