Sodium Metabisulfite CAS:7681-57-4

Sodium metabisulfite is an inorganic compound with the chemical formula Na2S2O5. It appears as a white crystalline powder or colorless transparent crystals. In air, sodium metabisulfite is easily oxidized to sodium sulfate, but the reaction is relatively slow. When dissolved in water, sodium metabisulfite decomposes into sodium bisulfite and sodium hydroxide, and its strong reducing properties make it widely used in various fields.

Sodium metabisulfite is most commonly used in the food industry as a preservative and antioxidant. It inhibits mold growth and slows oxidative spoilage of food, thereby extending shelf life.

Sodium metabisulfite is also an important raw material for reducing and bleaching agents in the printing and dyeing industries, and it can be used to bleach cotton, silk, and wool textiles.

Furthermore, it finds use in a variety of industries, including pharmaceuticals and textiles. For example, it can be used to make organic synthesis catalysts and reducing agents, as well as dyes. In the textile industry, it is used as a reducing agent during the dyeing process.
