Strontium diperchlorate

Strontium diperchlorate is an inorganic chemical compound with the molecular formula Cl2O8Sr and CAS number 13450-97-0. It belongs to the perchlorate family of compounds, containing strontium as the metallic cation paired with two perchlorate anions. With a molecular weight of 286.52 g/mol, this compound is classified as an oxidizing substance under ADR regulations (Class 5.1, Group II), indicating its potential to enhance combustion of other materials.

Strontium diperchlorate is typically found as a crystalline solid at room temperature. Like most perchlorates, it exhibits high solubility in water and forms clear solutions. The compound is hygroscopic, meaning it readily absorbs moisture from the atmosphere. As an ionic compound, it has a relatively high melting point and demonstrates good thermal stability under normal conditions, though it can decompose at elevated temperatures releasing oxygen.

Strontium diperchlorate is primarily used in pyrotechnic applications due to its oxidizing properties and ability to produce characteristic red flame coloration from the strontium ion. It serves as both an oxidizer and colorant in fireworks, flares, and signal devices. Additionally, it may be utilized in specialized chemical synthesis reactions where a strong oxidizing agent is required, and in certain analytical chemistry applications for strontium-based procedures.

Strontium diperchlorate requires careful handling as an oxidizing substance. Always wear appropriate personal protective equipment including safety goggles, chemical-resistant gloves, and protective clothing. Work in well-ventilated areas to avoid dust inhalation. Keep the compound away from combustible materials, reducing agents, and heat sources. Use non-sparking tools and avoid friction or impact during handling. Ensure proper grounding of equipment to prevent static electricity buildup during transfer operations.

Strontium diperchlorate must be stored in a cool, dry, well-ventilated area away from incompatible materials. Keep containers tightly sealed to prevent moisture absorption and contamination. Store separately from combustible materials, organic compounds, metals, and reducing agents. Use appropriate storage cabinets designed for oxidizing substances. Maintain storage temperature below 25°C and protect from direct sunlight. Regular inspection of containers for damage or contamination is essential for safe storage.

Strontium diperchlorate exposure requires immediate action depending on the contact route. For skin contact, remove contaminated clothing and rinse affected area thoroughly with water for at least 15 minutes. If inhaled, move to fresh air immediately and seek medical attention if breathing difficulties occur. For eye contact, flush eyes with clean water for 15 minutes while holding eyelids open. If ingested, rinse mouth and seek immediate medical attention without inducing vomiting.

Strontium diperchlorate disposal must comply with local and European waste regulations for oxidizing substances. The compound cannot be disposed of as regular waste due to its oxidizing properties. Contact licensed hazardous waste disposal companies for proper treatment. Small quantities may be neutralized through controlled reaction with reducing agents under professional supervision. Always consult local environmental authorities for specific disposal requirements and maintain proper documentation of waste disposal activities.

Strontium diperchlorate is classified under ADR as Class 5.1 (Oxidizing Substances), Packing Group II, indicating moderate danger level during transport. Packages must bear appropriate hazard labels and be constructed to prevent leakage and contamination. Use UN-approved packaging suitable for oxidizing substances. Transport vehicles must comply with ADR requirements including proper placarding, emergency equipment, and driver training. Segregation from incompatible materials during transport is mandatory for safety compliance.

Strontium diperchlorate is subject to various European chemical regulations including REACH registration requirements for commercial use. It falls under CLP regulation for classification and labeling of chemical substances. The compound is not currently listed as a Substance of Very High Concern (SVHC) under REACH. However, as an oxidizing substance, it may be subject to additional national restrictions regarding storage quantities, transportation, and use in certain applications depending on local legislation.

Strontium diperchlorate is available through OYSI, a specialized European distributor of technical chemicals. OYSI provides reliable supply chains for industrial and research applications across Europe, ensuring compliance with all relevant regulations including REACH and transportation requirements. Professional customers can contact OYSI for product specifications, safety documentation, and delivery options. As a regulated oxidizing substance, purchases may require appropriate licenses and end-user declarations depending on intended applications and quantities.
