Sodium Chlorite (NaClO2) CAS 7758-19-2

Product Overview

Sodium Chlorite (CAS 7758-19-2) is an inorganic chlorite oxidizer supplied in solid or aqueous grades for controlled industrial processes. It may be used to generate chlorine dioxide or in specified oxidation and bleaching systems only after concentration, process design, hazard controls and end-use authorization are confirmed.

Chemical identity alone does not establish suitability for drinking-water treatment, biocidal use, sanitation or a particular bleaching process. Confirm active sodium chlorite content, impurities, physical form, transport classification, required approvals and destination-market documentation for the offered grade.

Product Information / Specifications

Physical & Chemical Properties

Applications

• Controlled chlorine-dioxide generation only for a validated process and an appropriately documented grade
• Process oxidation in municipal or industrial treatment operations
• Bleaching applications in sectors where chlorine dioxide chemistry is required
• Odor control and sanitation-related treatment programs using controlled oxidizing systems
• Selected industrial processing systems requiring chlorite-based oxidizing performance

Quality Control and Procurement Documents

For sodium chlorite procurement, specify the NaClO2 mass fraction and whether the result is reported as received or on a dry basis. Iodometric titration is used for sodium chlorite assay; ion chromatography can determine chlorate and sulfate impurities. Agree the analytical methods, reporting basis and impurity limits for the supplied solid or solution grade. A sodium chlorite assay is not the same quantity as available chlorine.

We can provide a Certificate of Analysis (COA), Technical Data Sheet (TDS), Safety Data Sheet (SDS) and relevant quality-control reports for sodium chlorite, including ion-chromatography results where applicable to the agreed specification.

Related Water-Treatment and Bleaching Materials

For water-treatment procurement, ferric chloride and polyaluminum chloride (PAC) serve as coagulants in separate treatment stages. They do not replace sodium chlorite as a chlorine-dioxide precursor; concentrated treatment chemicals must not be mixed together.

For comparison with peroxide-based bleaching materials, see sodium percarbonate and sodium perborate tetrahydrate. Their chemistry and process requirements differ from chlorite-based systems, so they are not direct replacements.

Packaging

Confirm oxidizer-compatible packaging, transport classification and destination requirements

Packaging information may vary by grade, purity range, destination, and regulatory handling requirements.

Storage Conditions

• Store in a cool, dry, and well-ventilated area.
• Keep container tightly closed and protected from moisture.
• Keep away from acids, reducing agents, combustible materials, and organic substances.
• Avoid heat exposure and conditions that may promote decomposition.
• Use only compatible containers and handling systems suitable for oxidizing chemicals.

Safety Precautions

• Handle as a strong oxidizer under appropriate industrial safety procedures.
• Avoid inhalation of dust or mist and prevent contact with eyes, skin and clothing.
• Use suitable protective gloves, eye protection, protective clothing, and ventilation.
• Do not mix with acids, ammonia, reducing substances, or combustible materials.
• Refer to the latest SDS before storage, handling, transport, or process use.
