product description
Chemical Identity and Appearance: Sodium metabisulfite (CAS#7681-57-4) is an inorganic compound with the formula Na₂S₂O₅. It is typically supplied as a white crystalline powder. Purity and other quality parameters should be confirmed through the batch-specific certificate of analysis.
Odor and Handling Precautions: The material may have a pungent sulfur dioxide odor. Released sulfur dioxide can irritate the respiratory tract; avoid inhalation and use appropriate ventilation. Odor should not be used as a method of identification or a measure of safe exposure.
Thermal Decomposition: Sodium metabisulfite decomposes upon heating, releasing sulfur dioxide (SO₂). Contact with acids also releases SO₂ and requires appropriate handling controls.
Reducing Properties and Applications: Sodium metabisulfite is used as a reducing agent in chemical processing and in selected antioxidant, preservative, and bleaching applications. Suitability depends on the product grade, intended use, and applicable requirements.
