Dichloronickel

Dichloronickel is an inorganic chemical compound with the molecular formula Cl2Ni and CAS number 7718-54-9. This nickel salt has a molecular weight of 129.6 g/mol and is classified as a highly hazardous substance due to its carcinogenic, mutagenic, and reproductive toxic properties. It carries the GHS danger signal word and requires strict handling protocols in industrial applications.

Dichloronickel is typically found as a solid crystalline material at room temperature. As an anhydrous nickel chloride compound, it exhibits hygroscopic properties and is highly soluble in water and polar solvents. The compound appears as yellow-green crystals in its anhydrous form and demonstrates typical ionic compound characteristics with high melting and boiling points.

Dichloronickel is primarily used as a catalyst in organic synthesis reactions and as a precursor for preparing other nickel compounds. It serves as an important intermediate in electroplating processes, battery manufacturing, and specialized chemical syntheses. The compound is also utilized in research applications and as a starting material for producing nickel-based catalysts in industrial chemical processes.

Dichloronickel requires strict safety protocols due to its classification as Carc. 1A, Muta. 2, and Repr. 1B. Essential PPE includes respiratory protection, chemical-resistant gloves, safety goggles, and protective clothing. Work must be conducted in well-ventilated areas or under fume hoods. Avoid skin contact, inhalation, and ingestion. Regular health monitoring is recommended for workers exposed to this substance.

Dichloronickel must be stored in tightly sealed containers in a cool, dry, well-ventilated area away from incompatible materials. Due to its hygroscopic nature, moisture protection is essential. Storage areas should be secure with restricted access due to the substance's high toxicity classification. Keep away from heat sources, oxidizing agents, and ensure appropriate labeling with GHS pictograms GHS06, GHS08, and GHS09.

Dichloronickel exposure requires immediate action due to its acute toxicity. 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. In case of eye contact, flush with water for 15 minutes. For ingestion, do not induce vomiting and seek immediate medical help. Always consult emergency services for serious exposures.

Dichloronickel disposal must comply with hazardous waste regulations due to its high toxicity classification. The substance requires specialized hazardous waste treatment and cannot be disposed of through regular waste streams. Contact licensed hazardous waste disposal companies for proper collection and treatment. Ensure proper documentation and follow local environmental regulations for heavy metal-containing waste disposal.

Dichloronickel is classified under ADR Class 6.1 (Toxic substances), Packing Group III for transportation purposes. It requires appropriate hazardous goods packaging, labeling, and documentation according to dangerous goods regulations. Transporters must be certified for handling Class 6.1 materials and vehicles must display proper hazard placards. Shipping documentation must include safety data sheets and emergency response information.

Dichloronickel is subject to strict regulatory oversight under REACH and CLP regulations in Europe due to its classification as carcinogenic, mutagenic, and toxic for reproduction. While not currently listed as an SVHC, it requires safety data sheets, proper classification, and labeling. Industrial users must implement risk management measures and may need authorization for certain uses under chemical safety legislation.

Dichloronickel is available through OYSI, a European distributor of technical chemicals specializing in hazardous substances. As a professional chemical supplier, OYSI provides proper documentation, safety data sheets, and regulatory compliance support for dichloronickel purchases. Due to the substance's high hazard classification, sales are restricted to qualified industrial and research customers with appropriate handling capabilities.
