Cobalt(2+) diacetate

Cobalt(2+) diacetate is an inorganic salt compound with the molecular formula C4H6CoO4 and CAS number 71-48-7. It consists of cobalt in the +2 oxidation state combined with two acetate ions. With a molecular weight of 177.02 g/mol, this compound is classified as highly hazardous due to its carcinogenic, mutagenic, and reproductive toxicity properties. It also causes respiratory and skin sensitization and poses significant environmental risks to aquatic life.

Cobalt(2+) diacetate typically appears as pink or red crystalline solid at room temperature. It is highly soluble in water and polar solvents, forming characteristic pink-colored solutions. The compound is hygroscopic, meaning it readily absorbs moisture from air. It has good thermal stability under normal conditions but decomposes at elevated temperatures. The acetate groups provide the compound with relatively good solubility compared to other cobalt salts.

Cobalt(2+) diacetate serves as a catalyst in various industrial chemical processes, particularly in oxidation reactions and polymerization. It is used in the production of vitamins, especially vitamin B12 synthesis. The compound finds applications in ceramic and glass industries as a colorant, producing blue to pink hues. It is also utilized in electroplating processes and as a precursor for other cobalt compounds in research and industrial manufacturing.

Cobalt(2+) diacetate requires strict safety measures due to its carcinogenic and sensitizing properties. Mandatory personal protective equipment includes respiratory protection (P2/P3 masks), chemical-resistant gloves, safety goggles, and protective clothing. Work must be conducted in well-ventilated areas or under fume hoods. Avoid inhalation, skin contact, and ingestion. Regular health monitoring is essential for workers exposed to this substance. Emergency shower and eyewash stations should be readily accessible.

Cobalt(2+) diacetate must be stored in tightly sealed containers in a cool, dry, and well-ventilated area away from incompatible materials. Keep containers protected from moisture due to its hygroscopic nature. Storage areas should be equipped with appropriate ventilation systems and restricted access due to its hazardous classification. Maintain storage temperature below 25°C and protect from direct sunlight. Ensure proper labeling with GHS08 and GHS09 pictograms and safety information.

Cobalt(2+) diacetate exposure requires immediate action due to its toxic properties. For skin contact, remove contaminated clothing and rinse thoroughly with water for at least 15 minutes. If inhaled, move to fresh air immediately and seek medical attention. For eye contact, flush with water for at least 15 minutes and remove contact lenses if present. If ingested, do not induce vomiting and seek immediate medical attention. Always consult a physician after any exposure incident.

Cobalt(2+) diacetate disposal must comply with hazardous waste regulations due to its toxic and environmental hazard classification. The compound cannot be disposed of in regular waste streams and requires specialized hazardous waste treatment facilities. Contact licensed waste disposal companies for proper handling and disposal. Never discharge into sewers, soil, or water bodies due to its aquatic toxicity. Maintain proper documentation for waste tracking and regulatory compliance throughout the disposal process.

Cobalt(2+) diacetate is classified as ADR Class 9 (Miscellaneous dangerous substances), Packing Group III for transportation purposes. Packages must be properly labeled with appropriate hazard markings and documentation. Transport vehicles require proper ventilation and emergency equipment. Drivers must possess ADR certification for dangerous goods transport. Ensure packages are secured to prevent damage during transit and comply with quantity limitations for different transport categories.

Cobalt(2+) diacetate is subject to strict regulatory oversight under REACH and CLP regulations in Europe due to its hazardous properties. It requires safety data sheets compliant with current legislation and proper classification labeling. The compound may be subject to authorization requirements and usage restrictions in certain applications. Manufacturers and importers must maintain registration dossiers and comply with supply chain communication requirements. Regular monitoring of regulatory updates is essential for compliance.

Cobalt(2+) diacetate is available through specialized chemical distributors like OYSI, which serves the European market with technical-grade chemicals. Due to its hazardous classification, purchases typically require proper documentation, safety data sheets, and compliance with regulatory requirements. Buyers must demonstrate appropriate handling capabilities and intended use.
