Cadmium;formic acid

Cadmium formate is an inorganic salt compound with the molecular formula CH2CdO2 and CAS number 4464-23-7. It consists of cadmium metal combined with formic acid, forming a crystalline salt with a molecular weight of 158.44 g/mol. This substance is classified as highly hazardous due to its carcinogenic properties and acute toxicity. It poses significant health risks and environmental concerns, requiring strict handling protocols and safety measures during industrial use.

Cadmium formate is typically a white to off-white crystalline solid at room temperature. As a metal formate salt, it exhibits moderate solubility in water and polar solvents. The compound has a molecular weight of 158.44 g/mol and contains cadmium, which gives it its characteristic heavy metal properties. Its physical appearance may vary slightly depending on purity and crystal form, but it generally presents as a fine crystalline powder or small crystals.

Cadmium formate is primarily used in specialized industrial applications including analytical chemistry as a reagent, in certain electroplating processes, and as an intermediate in chemical synthesis. Due to its high toxicity and carcinogenic properties, its use is heavily restricted and limited to specific professional applications where safer alternatives are not available. Its applications are mainly confined to controlled laboratory and industrial environments with strict safety protocols.

Cadmium formate requires extreme safety precautions due to its carcinogenic and acutely toxic properties. Personnel must wear complete personal protective equipment including respiratory protection, chemical-resistant gloves, protective clothing, and eye protection. Work should be conducted in well-ventilated areas or under fume hoods to prevent inhalation exposure. Strict hygiene protocols must be followed, including thorough washing after handling and prohibition of eating, drinking, or smoking in work areas.

Cadmium formate must be stored in tightly sealed containers in a cool, dry, well-ventilated area away from incompatible materials. Storage areas should be secure and access-controlled due to the substance's high toxicity. Containers should be properly labeled with hazard warnings and kept away from heat sources, acids, and oxidizing agents. Regular inspection of storage containers is essential to prevent leaks or contamination, and storage areas should have appropriate spill containment measures.

Immediate action is critical in case of cadmium formate exposure. For skin contact, remove contaminated clothing and rinse affected area with plenty of water for at least 15 minutes. If inhaled, move the person to fresh air immediately and seek medical attention. In case of eye contact, flush with water for at least 15 minutes and remove contact lenses if present. For ingestion, do not induce vomiting and seek immediate medical attention. Always consult a physician after any exposure.

Cadmium formate disposal must comply with hazardous waste regulations due to its toxic and carcinogenic properties. The substance cannot be disposed of in regular waste streams and requires specialized hazardous waste treatment. Contact licensed hazardous waste disposal companies for proper collection and treatment. All contaminated materials including containers, protective equipment, and cleaning materials must also be treated as hazardous waste. Detailed waste documentation and tracking is typically required by environmental authorities.

Cadmium formate is classified under ADR Class 6.1 (toxic substances), Packing Group II, indicating high toxicity requiring special transport precautions. Transportation must comply with dangerous goods regulations including proper packaging, labeling with toxic hazard symbols, and appropriate shipping documentation. Only authorized carriers trained in hazardous materials transport should handle shipments. Packages must be secured to prevent damage during transit and emergency response information must accompany the shipment.

Cadmium formate is subject to extensive regulatory controls due to its carcinogenic and toxic properties. Under REACH and CLP regulations, it requires safety data sheets and hazard classification. The substance may be subject to authorization requirements and use restrictions due to its cadmium content. National regulations often impose additional controls on cadmium compounds including occupational exposure limits, waste disposal requirements, and potential import/export restrictions depending on jurisdiction.

Cadmium formate is available through OYSI, a European distributor of technical chemicals specializing in regulated and hazardous substances. As a controlled substance due to its toxicity, purchase typically requires demonstration of legitimate professional use and compliance with regulatory requirements. OYSI can provide guidance on regulatory compliance and proper handling procedures. Due to the substance's hazardous nature, quantities and availability may be subject to regulatory restrictions and verification of end-use applications.
