Sodium Disulfite
Sodium Disulfite, also known as Sodium Metabisulfite or Sodium Pyrosulfite, is an inorganic chemical compound with the chemical formula Na₂S₂O₅. It is a white to slightly yellowish crystalline powder commonly used in laboratory analysis, chemical preparation, water treatment, preservation studies, and scientific research involving sulfite compounds and reducing agents.
Product Specifications
Sodium Disulfite is an inorganic compound with the chemical formula Na₂S₂O₅ and CAS Number 7681-57-4. It is also commonly known as Sodium Metabisulfite or Sodium Pyrosulfite. It is typically supplied as a white to slightly yellowish crystalline powder with a characteristic sulfur dioxide odour. It is readily soluble in water and forms solutions containing bisulfite ions.
Sodium Disulfite is valued for its reducing, antioxidant, and preservative properties. Common laboratory applications include analytical chemistry procedures, redox reaction studies, chemical preparation, water treatment research, and experiments involving sulfite compounds. It is also used in specialised industrial applications, including food preservation, pharmaceutical manufacturing, photographic processing, textile treatment, and wastewater treatment.
Its reducing properties and ability to react with oxidising substances make Sodium Disulfite useful in analytical chemistry, inorganic chemistry, environmental research, and general laboratory applications. The appropriate grade and purity should be selected according to the requirements of the intended application.
KSFE Malaysia supplies laboratory chemicals and scientific products for research institutions, educational facilities, and general laboratory applications.
Safety Note: Sodium Disulfite may cause serious eye irritation and may irritate the skin and respiratory tract. It can release toxic sulfur dioxide gas when it comes into contact with acids or under certain decomposition conditions. Individuals sensitive to sulfites may experience allergic or respiratory reactions. Avoid inhaling dust and prevent direct contact with the eyes and skin. Do not mix with acids or incompatible oxidising agents. Handle it in a well-ventilated area using appropriate personal protective equipment, including safety goggles, chemical-resistant gloves, and protective clothing. Store in a tightly closed container in a cool, dry place away from moisture, acids, and incompatible substances. Follow the supplier's safety data sheet (SDS) for proper handling, storage, and disposal.
