Sodium bisulfite (CAS No. 1185-55-3) is an odorless white crystalline powder or granules. It is a versatile reducing agent and preservative widely used in a variety of industries, including food processing, photographic materials, textiles, paper, water treatment, and chemical synthesis.

Sodium bisulfite is chemically known as sodium hydrogen sulfite and is commercially available as a technical grade material. It is produced by the reaction of sulfur dioxide with sodium hydroxide in aqueous solution. It is also known as disodium hydrogen sulfite and sodium hydrogen sulfite.

Sodium bisulfite is a strong reducing agent with a wide range of uses, such as bleaching, dechlorinating, and preserving food and other products. It is used in the manufacture of dyes, pharmaceuticals, and photographic materials. It is also used as a preservative in food processing, as a bleaching agent in the paper industry, and as a dechlorinating agent in water treatment.

Sodium bisulfite is non-toxic and non-corrosive, making it a safe and economical choice for many applications. It is also non-flammable, stable under normal temperature and pressure, and has a long shelf life. It is soluble in water and has a pH of 5.5-7.5.

Sodium bisulfite can be used in many industries, including food processing, pharmaceuticals, photographic materials, textiles, paper, and water treatment. It is used in the production of dyes, as a preservative in food processing, as a bleaching agent in the paper industry, and as a dechlorinating agent in water treatment. Its safety and cost-effectiveness make it an ideal choice for many applications.
