Product Specifications

Sodium Dithionite is an inorganic compound with the chemical formula Na₂S₂O₄ and CAS Number 7775-14-6. It is typically supplied as a white to pale yellow crystalline powder with a characteristic sulfurous odour. It is soluble in water but may decompose when exposed to moisture, heat, or acidic conditions. Its stability depends on storage conditions and product formulation.

Sodium Dithionite is valued for its strong reducing properties and ability to participate in various chemical reduction reactions. Common laboratory applications include analytical chemistry procedures, reduction studies, inorganic chemistry experiments, chemical preparation, and research involving sulfur-based reducing agents. It is also used in specialised industrial applications, including textile bleaching, pulp and paper processing, dye reduction, and removal of certain oxidised substances.

Its reducing properties make Sodium Dithionite useful in analytical chemistry, inorganic chemistry, textile 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 Dithionite is a reducing agent that may decompose when exposed to moisture, heat, or acidic conditions, potentially releasing hazardous sulfur dioxide and other sulfur-containing decomposition products. It may undergo self-heating under certain conditions and can present a fire risk when contaminated with incompatible substances. Avoid contact with strong oxidising agents, acids, and excessive moisture. Do not inhale dust and prevent direct contact with the eyes and skin. 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, dry container away from heat, moisture, acids, and oxidising agents. Follow the supplier's safety data sheet (SDS) for proper handling, storage, and disposal.
