What is Sodium Dithionite? Sodium Dithionite (chemical formula Na₂S₂O₄) is a powerful reducing agent used in various chemical, industrial, and laboratory applications. It is typically available as a white to pale yellow crystalline powder that is highly soluble in water. Sodium Dithionite is valued for its ability to reduce a wide range of compounds, particularly in processes requiring the removal of oxygen or the reduction of metal ions. This compound is used in industries such as textile, paper, and chemical manufacturing. It is also known by alternate names such as Sodium Hydrosulphite.

Shipped from Manchester, UK Facility: Sourced and packaged in non-toxic, chemical-resistant containers to ensure safe handling and maintain product quality during transport.

Frequent Uses

Textile Industry
Widely used in the textile industry as a reducing agent for the dyeing and bleaching of fabrics. It is particularly effective in reducing dyes, such as indigo, to create lighter shades or for removing stubborn colours in the process of fabric treatment.

Paper and Pulp Industry
As a bleaching agent. It helps to reduce chlorine and other compounds in the pulp, resulting in brighter and whiter paper products. It is especially effective in the production of high-quality, bleached paper.

Chemical Manufacturing
A reducing agent in the synthesis of a variety of chemicals, particularly in the production of aldehydes, ketones, and other organic compounds. It is essential in chemical processes that require the removal of oxygen from molecules or the reduction of metal ions.

Gold Extraction
In the gold mining industry, it is used in the extraction of gold from ores. It helps to reduce gold from its oxidised form, making it easier to separate and recover the precious metal from ore.

Photographic Industry
Particularly in the development and processing of photographic film. It acts as a reducing agent in the chemical baths, helping to reduce silver halides to form the final image.

Agricultural Chemicals
In the synthesis of certain agricultural chemicals, where its reducing properties are employed in the production of pesticides, herbicides, and fungicides that require the reduction of specific compounds.

Rubber Industry
As a reducing agent in the production of certain rubber products, particularly in the preparation of certain types of synthetic rubbers, where it helps control the polymerisation process and improve material properties.
