Sodium Dithionite, identified by its CAS number 7775-14-6, is a cornerstone chemical with a fascinating array of properties that make it indispensable in numerous industrial sectors. Chemically represented as Na2S2O4, this compound is characterized by its molecular weight of approximately 174.10 g/mol. It typically presents as a white to grayish crystalline powder, possessing a faint sulfurous odor. While stable in dry air, its solutions are prone to decomposition, especially in the presence of heat or acids. This reactivity underscores its efficacy as a powerful reducing agent.

The primary utility of Sodium Dithionite lies in its strong reducing capabilities. In industrial dyeing, it’s instrumental in reducing insoluble vat dyes to their soluble leuco forms, allowing for even application and vibrant color saturation on fabrics. This makes it a critical component for textile manufacturers aiming for high-quality finishes. For those looking to buy Sodium Dithionite, understanding these applications helps in specifying the required grade and quantity.
