About Sodium Metabisulfite
Sodium Metabisulfite (CAS 7681-57-4) is a white, crystalline powder with a characteristic sulfurous odor. It is chemically synthesized by the reaction of sulfur dioxide with sodium carbonate or sodium hydroxide, resulting in a versatile compound that serves as a critical chemical intermediate in various manufacturing processes.
In the Indian market, this chemical is extensively consumed by the textile industry for neutralizing residual chlorine after bleaching processes. It also plays a vital role in water treatment facilities for dechlorination and in the paper and pulp industry as a bleaching auxiliary. Its food-grade variant is strictly regulated and used as a preservative in dried fruits and wine production.
When procuring Sodium Metabisulfite, buyers should prioritize suppliers who provide a Certificate of Analysis (COA) specifying purity levels and heavy metal content. Given its hygroscopic nature, it is essential to ensure that the material is sourced in moisture-proof packaging to prevent clumping and degradation during transit across different climatic zones in India.
