Sodium Chlorite Flakes 80% - Technical Grade

Product Overview

Sodium Chlorite Flakes 80% - Technical Grade is a white crystalline solid and a robust oxidizing agent designed for demanding industrial settings. The product is supplied as flakes with an assay of 79–81% NaClO₂, typically 80%, ensuring reliable oxidizing performance in downstream processes. Its solid form contributes to stable handling and storage in bulk or drum configurations, while its chemistry enables controlled chlorine dioxide generation when acidified, a feature leveraged across water treatment and chemical synthesis workflows. The material is characterized by a practical particle size distribution and moisture content aligned with technical-grade QC targets, supporting reproducible reaction kinetics and process control in plant-scale operations.

In addition to its primary oxidizing role, this technical-grade sodium chlorite is specified with stringent impurity limits to minimize process contaminants in critical applications. The product is suitable for use by trained personnel in industries requiring robust oxidants with clear quality specifications, and it is compatible with standard protective equipment and facility controls used in industrial chemical handling. The combination of high purity, stable solid form, and well-defined specifications helps operators achieve consistent results across batch processing, disinfection-related oxidations, and chemical synthesis steps that rely on controlled chlorine dioxide generation under acidic conditions.

• Oxidative Transformations – In synthetic workflows requiring selective oxidation capabilities with downstream acidification to generate ClO₂ in situ.
• Metal or Mineral Processing – Oxidizer for certain leaching or detoxification steps, conducted under controlled pH and temperature regimes.
• Chemical Milling and Surface Treatment – Oxidant-assisted surface modification where compatibility with process streams is required.
• Cleaning-in-Place (CIP) Systems – Support for sanitization cycles in food-contact or Pharma-adjacent environments when formulation is appropriate for downstream approvals.

Safety Precautions

Handle with care in a well-ventilated area, using appropriate PPE including chemical-resistant gloves, splash goggles, and a face shield as needed. Store the material in a cool, dry place away from direct sunlight, in containers made of HDPE or glass to minimize moisture uptake and avoid reactions. Keep the container tightly closed when not in use and ensure separation from acids or strong reducing agents to prevent hazardous reactions. Adequate ventilation and fume management are essential during handling and transfer operations to minimize inhalation risks.

In case of exposure, follow SDS guidance: the signal word is DANGER with Ox. Liq. 1, Skin Corr. 1B, and Eye Dam. 1 classifications. Emergency procedures include rinsing eyes for several minutes, washing skin with soap and water, moving exposed individuals to fresh air, and seeking medical attention for inhalation or ingestion exposure. Transport is UN 1496, Sodium Chlorite, Class 5.1, PG II. Always consult the Safety Data Sheet before use and adhere to storage conditions: away from acids and reducing agents, keep container closed, and avoid elevated temperatures and moisture ingress.
