Nickel(2+) diacetate

Nickel(2+) diacetate is an inorganic chemical compound with the molecular formula C4H6NiO4 and CAS number 373-02-4. This nickel salt has a molecular weight of 176.78 g/mol and appears typically as green crystalline solid. It is classified as a highly hazardous substance with carcinogenic, mutagenic, and reproductive toxicity properties. The compound is widely used in industrial applications but requires strict safety measures due to its severe health hazards including respiratory and skin sensitization potential.

Nickel(2+) diacetate is a green crystalline solid at room temperature with good water solubility. The compound has a molecular weight of 176.78 g/mol and contains two acetate groups bound to a nickel(II) ion. It is hygroscopic and can form hydrated forms under ambient conditions. The substance is stable under normal conditions but may decompose upon heating, releasing toxic fumes. Its solubility in water makes it readily bioavailable, contributing to its toxicological concerns.

Nickel(2+) diacetate is primarily used as a catalyst in various chemical synthesis processes and as a precursor for preparing other nickel compounds. It serves in electroplating applications, textile dyeing, and as a mordant in the printing industry. The compound is also utilized in the production of specialized ceramics and as a component in certain analytical reagents. Due to its hazardous properties, its use is increasingly restricted and requires specialized handling procedures in industrial settings.

Nickel(2+) diacetate requires strict safety protocols due to its carcinogenic and sensitizing properties. Personnel must wear appropriate respiratory protection, chemical-resistant gloves, and protective clothing to prevent skin and inhalation exposure. Work should be conducted in well-ventilated areas or under fume hoods. Avoid generating dust and ensure proper containment during handling. Regular health monitoring is recommended for workers exposed to this substance. Emergency shower and eyewash facilities must be readily accessible in work areas.

Nickel(2+) diacetate must be stored in a cool, dry, well-ventilated area away from incompatible materials such as strong acids, bases, and reducing agents. The substance should be kept in tightly sealed containers to prevent moisture absorption and contamination. Storage areas must be restricted to authorized personnel only, with appropriate warning signs and emergency procedures posted. Keep away from heat sources and ensure proper segregation from food, feed, and other consumer products. Regular container inspection is essential.

Immediate action is required upon contact with nickel(2+) diacetate due to its toxic and sensitizing properties. For skin contact, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. If inhaled, move the person to fresh air immediately and seek medical attention. For eye contact, flush with clean water for at least 15 minutes. In all cases of exposure, seek immediate medical attention and provide the safety data sheet to medical personnel.

Nickel(2+) diacetate must be disposed of as hazardous waste through licensed waste management facilities in accordance with local and European regulations. The substance cannot be discharged to sewers, water bodies, or regular waste streams due to its environmental toxicity and heavy metal content. Container residues require the same disposal considerations as the pure substance. Waste generators must maintain proper documentation and follow chain-of-custody procedures. Consult local environmental authorities for specific disposal requirements in your region.

Nickel(2+) diacetate is classified as ADR Class 9 (Miscellaneous dangerous goods), Packing Group III for transportation purposes. The substance must be packaged in UN-approved containers with proper labeling including GHS pictograms GHS07, GHS08, and GHS09. Transport documents must include the correct shipping name and hazard information. Drivers must carry appropriate emergency response information and personal protective equipment. Special handling procedures apply during loading, transport, and unloading to prevent environmental release and personnel exposure.

Nickel(2+) diacetate is subject to extensive European regulations including REACH registration requirements and CLP classification as Carcinogenic 1A, Mutagenic 2, and Reproductive toxicant 1B. The substance falls under various national occupational exposure limits and may be subject to authorization procedures under REACH. Manufacturing and use restrictions apply in many applications, particularly consumer products. Companies handling this substance must comply with worker protection regulations, environmental permits, and reporting requirements. Regular regulatory updates should be monitored as restrictions continue to evolve.
