Cadmium(2+) carbonate

Cadmium(2+) carbonate is an inorganic chemical compound with the formula CCdO3 and CAS number 513-78-0. This cadmium salt has a molecular weight of 172.42 g/mol and appears as a white crystalline solid. It is classified as a highly hazardous substance with multiple health risks including carcinogenicity, mutagenicity, and acute toxicity. The compound requires careful handling due to its serious environmental and health impacts.

Cadmium(2+) carbonate is a white crystalline solid at room temperature with no characteristic odor. The compound is poorly soluble in water but dissolves in acids, releasing carbon dioxide. It has a density higher than water and exhibits typical carbonate properties, decomposing upon heating to release CO2. The substance is stable under normal conditions but should be protected from acids and strong heating to prevent decomposition.

Cadmium(2+) carbonate is primarily used in specialized industrial applications including the production of cadmium-based pigments, ceramics, and glass manufacturing. It serves as a precursor for other cadmium compounds and may be used in electroplating processes. Due to its high toxicity and carcinogenic properties, its use is heavily restricted and limited to essential industrial applications where safer alternatives are not available.

Cadmium(2+) carbonate requires strict safety protocols including wearing appropriate respiratory protection, chemical-resistant gloves, and protective clothing. Work should be conducted in well-ventilated areas or under fume extraction systems to prevent inhalation exposure. Avoid eating, drinking, or smoking in work areas, and wash hands thoroughly after handling. Due to its carcinogenic and mutagenic properties, minimize exposure time and follow occupational exposure limits strictly.

Cadmium(2+) carbonate should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from incompatible materials such as acids, strong oxidizers, and reducing agents. Storage areas must be secure and restricted to authorized personnel only. Keep containers properly labeled and maintain an inventory log. Store away from food, feed, and drinking water sources, and ensure spill containment measures are in place.

Immediate medical attention is required for any exposure to cadmium(2+) carbonate. For skin contact, remove contaminated clothing and wash affected areas thoroughly with soap and water. In case of eye contact, flush with clean water for at least 15 minutes. If inhaled, move to fresh air immediately and seek medical help. For ingestion, do not induce vomiting and contact poison control immediately. Always inform medical personnel about the specific substance involved.

Cadmium(2+) carbonate must be disposed of as hazardous waste through licensed waste management companies specialized in toxic metal compounds. The substance cannot be disposed of in regular waste streams due to its carcinogenic properties and environmental toxicity. Follow local and European waste regulations (EU Waste Framework Directive) and maintain proper documentation for waste tracking. Never discharge into sewers, waterways, or soil.

Cadmium(2+) carbonate is classified under ADR class 6.1 (toxic substances) with packing group III, indicating moderate toxicity for transport purposes. Packages must be properly labeled with appropriate hazard labels and UN identification numbers. Use approved packaging materials and ensure proper documentation including transport documents and emergency response information. Transport should only be conducted by trained personnel familiar with dangerous goods regulations.

Cadmium(2+) carbonate is subject to strict European regulations under REACH and CLP regulations due to its classification as carcinogenic 1B, mutagenic 1B, and toxic for reproduction. The substance faces significant restrictions on marketing and use under REACH Annex XVII. It requires safety data sheets, proper classification and labeling, and may need authorization for certain uses. Occupational exposure limits and environmental protection measures also apply.

Cadmium(2+) carbonate is available through specialized chemical distributors like OYSI, which supplies industrial chemicals across Europe. Due to regulatory restrictions and safety requirements, this substance is only sold to qualified industrial users with proper licenses and safety protocols. Customers must demonstrate legitimate industrial use and comply with applicable regulations. Contact OYSI directly to discuss availability, documentation requirements, and regulatory compliance for your specific application.
