Sodium Metabisulfite is also named Sodium Pyrosulfite, Sodium Metabisulfite is white or slight yellow crystalline powder, with strong smell of SO2, the proportion of 1.4, soluble in water, aqueous solution of Sodium Metabisulfite is acidic, Sodium Metabisulfite contacts with strong acids, released SO2 and generates sodium sulfate, commonly known as Glauber's salt. For a long time in the air, Sodium Metabisulfite can be oxidized into Na2S2O6, so Sodium Metabisulfite can not be stored for a long time. Above 150 degrees Celsius, Sodium Metabisulfite can decompose of SO2. Soluble in water and glycerin, slightly soluble in ethanol. Soluble in water, Sodium Metabisulfite generates into stable sodium bisulfite, pH under 1% aqueous solution ranged from 4.0 to 5.5.

Sodium Metabisulfite products are classified into Sodium Metabisulfite food grade and Sodium Metabisulfite industrial grade, with different quality index. Industrial grade Sodium Metabisulfite is mainly used in chemical, pharmaceutical, rubber, leather, printing and dyeing, and other industries. Food grade Sodium Metabisulfite is used in food industry. In food industry, in order to improve the food color, smell, taste and quality, as well as the demand to preserve, fresh and processing technology, food additives are often added. Sodium Metabisulfite is a kind of food additive, which is used as a preservative, antioxidant in food processing.
Industrial grade Sodium Metabisulfite has a wide uses range. In pharmaceutical industry Sodium Metabisulfite is used for purification in chloroform, benzene propyl sulfone and benzaldehyde production; Sodium Metabisulfite is used for coagulant in rubber industry; Sodium Metabisulfite is used for antichlor in cotton bleaching, Cotton mill auxiliary and mordant in printing and dyeing industry; Sodium Metabisulfite is used for leather processing in tanning industry, Sodium Metabisulfite can make leather soft, plump and tough, and make leather own waterproof, anti folding, wear resistance properties; Sodium Metabisulfite can be used for the production of Hydroxyvanilline and Hydroxylamine Hydrochloride in chemical industry; Sodium Metabisulfite can be used as developer in photographic industry.
