Sodium Formaldehyde Sulfoxylate (SFS), often recognized by its trade name Rongalite, is a chemical compound that offers a unique combination of properties making it invaluable across a spectrum of industrial applications. Understanding its chemical nature—its formula, appearance, and reactivity—is crucial for procurement professionals and chemists aiming to leverage its capabilities effectively. As a leading chemical supplier, we aim to provide clarity on this versatile compound.

The chemical formula of Sodium Formaldehyde Sulfoxylate is typically represented as CH3NaO3S. It is commonly available as a white lump or powder, possessing a mild odor often described as resembling leeks. Its solubility in water is notably high, allowing for easy incorporation into various aqueous-based processes. A key characteristic of SFS is its role as a potent reducing agent. This property underpins its widespread use in industries where controlled reduction or bleaching is required.

One of the most significant applications for SFS is in the textile industry, particularly in vat dyeing processes. Here, it functions as a reducing agent to solubilize vat dyes, enabling them to penetrate textile fibers. Once the dye is within the fiber, it can be re-oxidized to its insoluble form, ensuring vibrant and long-lasting colors. Manufacturers looking to buy Sodium Formaldehyde Sulfoxylate for textile applications often seek high-purity grades (e.g., 98% Min) to ensure consistent dyeing results and avoid unwanted side reactions.

Beyond textiles, SFS serves as a critical component in redox-initiation systems used in emulsion polymerization. These systems are vital for producing a wide range of polymers used in coatings, adhesives, and plastics. Its ability to generate free radicals at relatively low temperatures makes it an efficient initiator. Additionally, SFS finds application as an antioxidant in pharmaceutical formulations, contributing to the stability and shelf-life of certain medicinal products. Its role in water treatment, where it neutralizes chlorine and chloramine, further highlights its versatility.
