Copper selenite

Copper selenite is an inorganic chemical compound with the molecular formula CuO3Se and CAS number 10214-40-1. This compound consists of copper in combination with selenite ions, forming a salt-like structure. With a molecular weight of 190.52 g/mol, copper selenite belongs to the family of metal selenites and exhibits properties characteristic of both copper and selenium chemistry.

Copper selenite is a solid inorganic compound at room temperature, typically appearing as crystalline material. As a metal selenite, it exhibits limited solubility in water and most organic solvents. The compound is stable under normal conditions but may decompose at elevated temperatures. Its physicochemical behavior is influenced by both the copper cation and selenite anion components.

Copper selenite is primarily used in specialized chemical applications and research contexts. It serves as a source of both copper and selenium in various chemical syntheses and analytical procedures. The compound finds applications in materials science research, specialized catalyst preparation, and as a reagent in inorganic chemistry studies where controlled release of copper and selenium ions is required.

Copper selenite should be handled with appropriate personal protective equipment including gloves, safety glasses, and protective clothing. Work should be conducted in well-ventilated areas or under fume extraction to avoid inhalation of particles. Given its ADR classification as Class 6.1 Group I, it requires careful handling as a toxic substance. Avoid skin contact and ingestion, and wash hands thoroughly after handling.

Copper selenite should be stored in tightly sealed containers in a cool, dry, and well-ventilated area away from incompatible materials. Keep containers protected from physical damage and moisture. Storage areas should be secure and accessible only to authorized personnel. Maintain proper labeling and inventory records, and ensure storage conditions comply with local regulations for toxic substances.

In case of skin contact with copper selenite, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water. If eye contact occurs, flush immediately with clean water for at least 15 minutes and seek medical attention. In case of inhalation, move to fresh air immediately. If ingestion occurs, do not induce vomiting and seek immediate medical attention.

Copper selenite disposal must comply with local and national hazardous waste regulations due to its toxic classification. The compound should not be disposed of in regular waste streams or sewage systems. Contact licensed hazardous waste disposal companies for proper treatment and disposal. Small quantities may require special collection procedures, while larger amounts need professional hazardous waste management services.

Copper selenite is classified under ADR as Class 6.1 (toxic substances) Group I, indicating high toxicity requiring stringent transport controls. It must be packaged in UN-approved containers with proper hazard labels and documentation. Transport requires compliance with dangerous goods regulations, including driver training, vehicle marking, and emergency response procedures. Professional dangerous goods carriers should handle transportation.

Copper selenite is subject to various chemical regulations including REACH registration requirements in Europe and CLP classification rules. While not currently listed as a SVHC (Substance of Very High Concern), it falls under general chemical safety legislation due to its toxic properties. Users must comply with occupational safety regulations, environmental protection laws, and proper chemical management protocols.
