Description

Sodiumhypochloriteheptahydrate CAS NO 64131-03-9 is the heptahydrate crystalline form of sodium hypochlorite, a powerful and versatile oxidizing agent. This compound is valued for its controlled release of active chlorine, offering a more stable and solid alternative to liquid bleach solutions for specialized industrial applications. It is essential for manufacturers and research facilities requiring a precise, solid-state source of hypochlorite for synthesis, disinfection, and oxidation processes.

Application

• Industrial Water Treatment: Used as a solid biocide and oxidizing agent in cooling towers, process water, and wastewater treatment systems.
• Chemical Synthesis: Serves as a selective oxidizing agent in the production of pharmaceuticals, agrochemicals, and fine chemicals.
• Pulp & Paper Bleaching: Employed in bleaching sequences for pulp to achieve high brightness with controlled chlorine release.
• Textile Processing: Applied in the bleaching and desizing of natural fibers like cotton and linen.
• Sanitization & Disinfection: Formulated into solid cleaning products, disinfectant tablets, and specialty sanitizers for institutional and industrial use.
• Laboratory Research: Utilized as a standardized reagent for oxidation studies and analytical chemistry applications.

Quality Control

Our Sodium Hypochlorite Heptahydrate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure consistent purity, active chlorine content, and stability. Certificates of Analysis (COA) detailing assay, impurity profiles, and physical specifications are provided to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and incompatible materials such as acids, reducing agents, and organic compounds. Due to its oxidizing nature and sensitivity to light and heat, storage temperatures should be maintained below 25°C (77°F) to minimize decomposition.
