Diiodonickel

Diiodonickel is an inorganic chemical compound with the molecular formula I2Ni and CAS number 13462-90-3. This nickel halide has a molecular weight of 312.502 g/mol and appears as a crystalline solid. It is classified as a highly hazardous substance with multiple health and environmental risks, including carcinogenic, mutagenic, and reproductive toxicity properties. The compound requires careful handling due to its dangerous classification under GHS regulations.

Diiodonickel is a solid crystalline compound at room temperature with the molecular formula I2Ni. As a nickel iodide, it typically appears as dark-colored crystals and is hygroscopic, meaning it absorbs moisture from air. The compound has limited solubility in water but may dissolve in certain polar solvents. Its molecular weight is 312.502 g/mol, and it decomposes at elevated temperatures releasing toxic iodine vapors.

Diiodonickel is primarily used as a catalyst in organic synthesis reactions, particularly in cross-coupling reactions and organometallic chemistry. It serves as a nickel source in various chemical processes and can be employed in the preparation of other nickel compounds. The substance finds applications in research laboratories and specialized industrial processes where nickel-based catalysts are required for specific chemical transformations.

Diiodonickel must be handled with extreme caution due to its carcinogenic and toxic properties. Essential protective equipment includes respiratory protection with appropriate filters, chemical-resistant gloves, safety goggles, and protective clothing. Work should be conducted in well-ventilated areas or under fume hoods to prevent inhalation exposure. Avoid skin contact and ingestion completely. Personnel should be trained in hazardous material handling procedures before working with this substance.

Diiodonickel should be stored in tightly sealed, labeled containers in a cool, dry, well-ventilated area away from incompatible materials. Keep containers away from heat sources, direct sunlight, and moisture due to its hygroscopic nature. Store separately from oxidizing agents, acids, and organic materials. Access should be restricted to authorized personnel only, and storage areas must comply with local regulations for carcinogenic substances.

Immediate action is required for any contact with diiodonickel. For skin contact, remove contaminated clothing and wash affected area thoroughly with soap and water for at least 15 minutes. If inhaled, move to fresh air immediately and seek medical attention. For eye contact, flush with clean water for 15 minutes. In case of ingestion, do not induce vomiting and seek immediate medical care. Always consult a physician after any exposure incident.

Diiodonickel must be disposed of as hazardous waste through licensed waste management companies specializing in heavy metal and toxic substance disposal. Never dispose of it in regular waste streams or pour down drains. The disposal method should comply with local environmental regulations and waste classification requirements. Recovery or recycling of nickel content may be possible through specialized facilities. Proper documentation and waste tracking are mandatory.

Diiodonickel is classified under ADR Class 9 (Miscellaneous dangerous goods), Packing Group III for transportation purposes. It requires appropriate hazardous material packaging, labeling with GHS08 and GHS09 pictograms, and proper shipping documentation. Transport should only be conducted by certified carriers familiar with dangerous goods regulations. Packages must be secured to prevent damage during transit and marked with the correct identification numbers and hazard labels.

Diiodonickel is subject to strict regulations under REACH and CLP in Europe due to its classification as Carcinogenic 1A, Mutagenic 2, and Reproductive toxicant 1B. It requires safety data sheets, proper labeling with danger signal word, and specific risk management measures. Users must comply with occupational exposure limits and workplace safety regulations. Import/export may require permits, and use restrictions may apply depending on the application and jurisdiction.

Diiodonickel is available through OYSI, a European distributor of specialized chemical products. As a regulated substance, purchases typically require verification of legitimate use and compliance with safety regulations. OYSI can provide proper documentation, safety data sheets, and technical support for this hazardous material.
