Sodium metabisulphite ≥97% ACS
Sodium metabisulphite
Sodium metabisulfite is an antioxidant reducing agent, with antimicrobial and antifungal properties. Gastric tissue studies report that sodium metabisulfite can augment lipid peroxidation and apoptosis in a dose-dependent manner.

Sodium metabisulfite is used as an active ingredient in campden tablets, as a cleaning agent for potable water reverse osmosis membranes, as a preservative and an antioxidant in food. It also acts as a corrosion inhibitor in oil and gas industry, as a bleaching agent in the production of coconut cream, as the source of sulfur dioxide and in the destruction of cyanide in commercial gold cyanidation processes. It is utilized in the precipitation of gold from auric acid as well as in the waste water treatment to remove hexavaent chromium as trivalent chromium by precipitation after reduction. Further, it is used in photography. In addition, it plays as an oxygen scavenger to eliminate the dissolved oxygen in wastewater and in pipes.
