Sodium bisulfite is a sodium-based compound commonly used as a reducing agent and preservative across multiple industries. It plays an important role in water treatment, where it removes excess chlorine, and in chemical manufacturing, where it supports various synthesis and processing steps. Its effectiveness as an antioxidant also makes it valuable in certain food and beverage applications.
Beyond these uses, sodium bisulfite is employed in detergents, pulp and paper production, textiles, and specialty chemical formulations. Its versatility allows it to serve everything from bulk industrial operations—such as large-scale water treatment facilities and paper mills—to smaller, specialized markets including food preservation, pharmaceuticals, and cosmetics.
