Sodium Metabisulfite (CAS 7631-90-5) is an inorganic compound celebrated for its distinct chemical properties, particularly its potent reducing and antioxidant capabilities. These characteristics make it a highly sought-after chemical intermediate across a spectrum of industrial applications, from food preservation to advanced chemical synthesis. As a leading manufacturer and supplier based in China, we provide a detailed understanding of its chemical behavior to assist researchers and procurement managers in optimizing their use of this versatile substance.

The core chemical identity of Sodium Metabisulfite is tied to its ability to release sulfur dioxide (SO2) when dissolved in water or exposed to acidic conditions. This reaction forms sodium bisulfite (NaHSO3), which is the active species responsible for its reducing and bleaching actions. For instance, in aqueous solutions, it readily reacts with oxidizing agents, effectively neutralizing them. This property is leveraged in applications such as removing residual chlorine from water or acting as a preservative by scavenging oxygen. When seeking to buy Sodium Metabisulfite, understanding this reactivity is crucial for safe handling and effective application.

As an antioxidant, Sodium Metabisulfite inhibits oxidation reactions, which is vital in preserving the quality and appearance of various products. In the food industry, this prevents enzymatic browning in fruits and the degradation of sensitive ingredients. In pharmaceuticals, it helps maintain the stability of certain drug formulations. The consistent high purity (typically 99% min) of Sodium Metabisulfite supplied by us ensures reliable performance in these demanding roles. Manufacturers and formulators can trust our product as a foundational chemical intermediate.

Furthermore, its role as a reducing agent extends to complex chemical syntheses and industrial processes like textile bleaching and photographic development. The ability to cleave disulfide bonds or reduce metal ions highlights its chemical utility. For businesses looking for a stable and effective reducing agent, sourcing Sodium Metabisulfite from a reputable manufacturer like us in China provides a cost-effective and quality-assured solution. We encourage prospective clients to inquire about our pricing and bulk purchase options to experience the benefits of our manufacturing expertise.
