Strontium oxoarsinite

Strontium oxoarsinite is an inorganic compound with the chemical formula As2O4Sr and CAS number 91724-16-2. This arsenic-containing compound has a molecular weight of 301.46 g/mol and consists of strontium combined with arsenic oxides. It belongs to the family of metal arsenites and is classified as a toxic substance for transportation purposes under ADR regulations as class 6.1, packing group II, indicating its hazardous nature.

Strontium oxoarsinite presents specific physicochemical characteristics typical of inorganic metal arsenites. As an inorganic compound with molecular formula As2O4Sr, it likely exists as a solid at room temperature with limited water solubility. The compound contains arsenic in its structure, which influences its chemical behavior and stability. Specific properties such as exact melting point, density, and detailed solubility data would require laboratory analysis for precise determination.

Strontium oxoarsinite serves specialized applications in industrial and research settings due to its unique chemical composition containing both strontium and arsenic components. Its specific uses may include research applications in materials science, potential applications in specialized chemical synthesis, or as an intermediate in the production of other strontium or arsenic-containing compounds. Given its toxic classification, its applications are typically limited to controlled industrial or laboratory environments with appropriate safety measures.

Strontium oxoarsinite requires careful handling due to its ADR class 6.1 toxic classification. Essential safety measures include wearing appropriate personal protective equipment such as chemical-resistant gloves, safety goggles, and respiratory protection when handling this compound. Work should be conducted in well-ventilated areas or under fume extraction systems. Avoid direct contact with skin, eyes, and inhalation of dust or particles. Ensure proper training and follow established safety protocols for toxic substances.

Strontium oxoarsinite must be stored in secure, dry conditions away from incompatible materials and moisture sources. Storage areas should be well-ventilated, temperature-controlled, and restricted to authorized personnel only due to its toxic nature. Use appropriate containment systems with proper labeling indicating the toxic hazard. Keep containers tightly sealed and store separately from food, feed, and other consumables. Regular inspection of storage containers and conditions is recommended to prevent deterioration or contamination.

Immediate action is required following any contact with strontium oxoarsinite due to its toxic properties. In case of skin contact, remove contaminated clothing and rinse affected areas thoroughly with water for at least 15 minutes. For eye contact, flush immediately with clean water and seek medical attention. If inhaled, move to fresh air immediately. In case of ingestion, do not induce vomiting and seek immediate medical attention. Always consult a physician and provide the safety data sheet.

Strontium oxoarsinite requires specialized disposal procedures as hazardous waste due to its toxic classification and arsenic content. Disposal must comply with local, national, and European waste regulations for toxic substances. Contact licensed hazardous waste disposal companies for proper treatment and disposal. Never dispose of in regular waste streams, sewers, or the environment. Maintain proper documentation of waste disposal activities and ensure containers are properly labeled as toxic waste before collection by authorized waste management services.

Strontium oxoarsinite is classified under ADR regulations as class 6.1 (toxic substances), packing group II, requiring specific transport protocols. Transportation must comply with dangerous goods regulations using appropriate packaging, labeling, and documentation. Only authorized carriers with proper training and equipment should handle transport. Vehicles must display appropriate hazard placards and carry emergency response information. Ensure proper securing of packages and avoid transport with incompatible materials or food products.

Strontium oxoarsinite is subject to various European chemical regulations including REACH registration requirements and CLP classification and labeling provisions. Its toxic nature and arsenic content may trigger additional regulatory oversight under substance-specific restrictions. The compound is not currently listed as a Substance of Very High Concern (SVHC), but users must comply with occupational health and safety regulations. Regular monitoring of regulatory updates is recommended as classifications and restrictions can change.

Strontium oxoarsinite is available through specialized chemical distributors in Europe, including OYSI, which serves as a reliable European supplier of technical chemicals. Due to its toxic classification, procurement typically requires proper authorization, safety documentation, and compliance with regulatory requirements. Buyers should ensure they have appropriate handling facilities, trained personnel, and necessary permits before ordering.
