Zinc dibromate

Zinc dibromate is an inorganic compound with the chemical formula Br2O6Zn and CAS number 14519-07-4. This chemical substance has a molecular weight of 321.2 g/mol and belongs to the category of metal bromate salts. It is classified as an oxidizing substance under ADR transport regulations (Class 5.1, Group III), indicating its ability to support combustion and potentially intensify fires involving other materials.

Zinc dibromate is a crystalline solid compound that typically appears as white to pale yellow crystals or powder. As a bromate salt, it demonstrates oxidizing properties and is generally soluble in water, forming clear solutions. The compound is stable under normal conditions but can decompose when heated to high temperatures, potentially releasing toxic bromine compounds and oxygen gas.

Zinc dibromate is primarily used as an oxidizing agent in various chemical processes and analytical applications. Its oxidizing properties make it valuable in laboratory synthesis reactions, analytical chemistry procedures, and specialized industrial processes requiring controlled oxidation. The compound may also serve as a reagent in research applications and specific chemical manufacturing processes where precise oxidation conditions are required.

Zinc dibromate should be handled with appropriate personal protective equipment including safety goggles, chemical-resistant gloves, and protective clothing. Work in well-ventilated areas or under fume extraction to avoid inhalation of dust particles. As an oxidizing substance, keep it away from combustible materials, reducing agents, and heat sources. Use non-sparking tools and ensure proper grounding when handling to prevent static electricity buildup.

Zinc dibromate must be stored in a cool, dry, well-ventilated area away from heat sources and direct sunlight. Keep containers tightly closed and store separately from combustible materials, organic compounds, reducing agents, and acids. Use appropriate storage cabinets designed for oxidizing substances. Ensure storage areas are equipped with appropriate fire suppression systems and maintain ambient temperatures to prevent decomposition.

Zinc dibromate contact requires immediate action depending on exposure type. For skin contact, remove contaminated clothing and rinse thoroughly with water for at least 15 minutes. If eye contact occurs, flush immediately with clean water for 15-20 minutes and seek medical attention. In case of inhalation, move to fresh air immediately. For ingestion, do not induce vomiting and seek immediate medical assistance.

Zinc dibromate disposal must comply with local and national hazardous waste regulations. This oxidizing substance cannot be disposed of through regular waste streams and requires specialized hazardous waste treatment. Contact licensed hazardous waste disposal companies for proper collection and treatment. Small laboratory quantities may require neutralization procedures before disposal, following institutional waste management protocols and environmental regulations.

Zinc dibromate is classified under ADR as Class 5.1 (Oxidizing Substances), Group III for transportation purposes. This classification requires specific packaging, labeling, and documentation for road transport within Europe. Packages must display appropriate hazard labels and be constructed to prevent leakage and contamination. Transport vehicles must carry appropriate emergency equipment and documentation, and drivers require ADR certification for handling oxidizing substances.

Zinc dibromate is subject to standard chemical regulations including REACH registration requirements for importers and manufacturers in the European Union. The substance is not currently listed as a Substance of Very High Concern (SVHC) under REACH. However, as a chemical product, it must comply with CLP regulation for classification, labeling, and packaging, along with local occupational health and safety regulations.

Zinc dibromate is available through specialized chemical distributors in Europe, including OYSI, a professional distributor of technical chemicals. OYSI provides zinc dibromate to industrial customers, research institutions, and laboratories across European markets. When purchasing, ensure the supplier provides proper documentation including safety data sheets, certificates of analysis, and compliance with REACH registration requirements for professional use applications.
