Potassium bromate

Potassium bromate is an inorganic oxidizing compound with the chemical formula BrKO3 and CAS number 7758-01-2. This white crystalline salt has a molecular weight of 167 g/mol and serves primarily as a powerful oxidizing agent in various industrial applications. It is classified as a dangerous substance due to its oxidizing properties, acute toxicity, and carcinogenic potential, requiring careful handling and strict safety measures in professional environments.

Potassium bromate is a white crystalline solid that is highly soluble in water, forming clear solutions. It is odorless and stable under normal conditions but decomposes when heated, releasing oxygen and forming potassium bromide. As a strong oxidizing agent, it readily reacts with organic materials and reducing substances. The compound has good thermal stability at room temperature but becomes increasingly reactive at elevated temperatures, making proper storage conditions essential.

Potassium bromate is primarily used as an oxidizing agent in analytical chemistry and laboratory applications. It serves as a reagent in volumetric analysis and redox titrations. In industrial settings, it functions as an oxidizer in various chemical processes and synthesis reactions. Due to its strong oxidizing properties, it is also employed in specialized manufacturing processes where controlled oxidation is required, though its use is restricted in many applications due to safety concerns.

Potassium bromate requires strict safety measures including wearing protective gloves, safety goggles, and protective clothing to prevent skin and eye contact. Work in well-ventilated areas or under fume hoods to avoid inhalation of dust particles. Keep the substance away from heat sources, combustible materials, and reducing agents. Use non-sparking tools and ensure proper grounding to prevent static electricity buildup. Always wash hands thoroughly after handling and never eat, drink, or smoke in work areas.

Potassium bromate must be stored in a cool, dry, well-ventilated area away from heat sources and direct sunlight. Keep containers tightly sealed and separate from incompatible materials such as organic compounds, reducing agents, and combustible substances. Storage areas should be equipped with appropriate fire suppression systems and emergency equipment. Ensure proper labeling and maintain inventory records. Store in original containers or approved alternatives, and regularly inspect containers for damage or deterioration.

Potassium bromate exposure requires immediate action: for skin contact, remove contaminated clothing and rinse affected area with plenty of water for at least 15 minutes. In case of eye contact, flush immediately with clean water for 15 minutes while holding eyelids open. If inhaled, move the person to fresh air and monitor breathing. For ingestion, do not induce vomiting and seek immediate medical attention. Always consult a physician after any exposure and provide the safety data sheet to medical personnel.

Potassium bromate disposal must comply with local, national, and EU waste regulations as it is classified as hazardous waste. Never dispose of it through regular waste streams or pour it down drains. Contact licensed hazardous waste disposal companies for proper collection and treatment. Small quantities can be neutralized by qualified personnel following approved procedures, but this should only be done by trained professionals. Maintain proper documentation of all disposal activities and ensure containers are properly labeled before disposal.

Potassium bromate is classified under ADR as Class 5.1 (Oxidizing substances) Packing Group II, requiring specialized transport procedures. It must be packaged in UN-approved containers with proper hazard labels and documentation. Transport vehicles need appropriate placarding and drivers require ADR certification. The substance cannot be transported with incompatible materials and requires proper segregation. Emergency response information must accompany shipments, and transport should follow designated routes when required by local regulations.

Potassium bromate is subject to strict European regulations under REACH and CLP due to its classification as Carcinogenic 1B, Acute Toxic 3, and Oxidizing Solid 1. It requires safety data sheets, proper labeling with danger pictograms (GHS03, GHS06, GHS08), and the signal word "Danger." Professional users must implement risk management measures and may need authorization for certain uses. Its use is restricted or banned in food applications in many countries due to carcinogenic properties.

Potassium bromate is available through OYSI, a European distributor of technical chemicals serving industrial and professional customers. As a regulated substance, purchases typically require documentation of intended use and compliance with safety regulations. OYSI provides proper packaging, labeling, and documentation to ensure regulatory compliance throughout Europe. Professional buyers should verify local restrictions and requirements before ordering, as availability may vary by country due to regulatory limitations on this hazardous substance.
