Product Description

Product Overview
Sodium Sulphite (Na2SO3) is a versatile chemical compound used across various industries including food processing, water treatment, photography, and chemical manufacturing. With a minimum assay of 97%, this compound offers compositional accuracy and purity for specialized industrial uses.

Applications
Commonly used in the pulp and paper industry as a reducing agent and bleaching aid, Sodium Sulphite also serves as an antichlor in water treatment systems. In photography, it acts as a preservative and antioxidant. It is used as an enzyme inhibitor in food and drug processing, and as an oxygen scavenger in oil well floatation and boiler water systems.

Performance & Benefits
This food/photo-grade powder features a low impurity profile, with sulphate content ≤ 2.5%, iron ≤ 10 ppm, and heavy metals ≤ 20 ppm. It is free from contamination, has minimal moisture content (≤ 0.1%), and remains stable during storage and transportation.

Specifications
- Assay: ≥ 97% - Sulphate: ≤ 2.5% - Insolubles: ≤ 0.1% - Moisture: ≤ 0.1% - Iron (Fe): ≤ 10 ppm - Heavy Metals (Pb): ≤ 20 ppm - Form: Powder - CAS No.: 7757-83-7

Supply & Export Readiness
