Product Description

Product Description: Sodium Pyrosulfite

Product Name: Sodium Pyrosulfite

CAS Number: 7681-57-4

Molecular Formula: Na2S2O5

Molecular Weight: 190.10 g/mol

Appearance: White or nearly white, crystalline powder or small crystals with a strong odor of sulfur dioxide (SO2).

Melting Point: Decomposes at approximately 150°C

Density: 1.48 g/cm³

Solubility: Soluble in water (540 g/L at 20°C), soluble in glycerin, slightly soluble in ethanol.

Product Description: Sodium pyrosulfite is a highly adaptable reducing agent favored in various industries for its robust reducing properties. Presented as a white crystalline powder, it swiftly dissolves in water to create acidic solutions. Upon heating beyond 150°C, the compound begins to decompose, releasing sulfur dioxide gas.

Applications:

  • Brewing and Winemaking: Utilized as a preservative to prevent oxidation and spoilage.
  • Food Processing: Functions as a bleaching agent and preservative in an array of food products.
  • Pharmaceuticals: Used as a reducing agent in the production of various drugs.
  • Chemical Synthesis: Employed in the synthesis of dyes, pharmaceuticals, and other chemicals.
  • Textile Industry: Acts as a reducing agent in dyeing processes and a bleaching agent for fabrics.
