Nickel(2+) diformate

Nickel(2+) diformate is an inorganic nickel salt with the molecular formula C2H2NiO4 and CAS number 3349-06-2. This chemical compound has a molecular weight of 148.73 g/mol and consists of a divalent nickel cation complexed with two formate anions. It belongs to the family of nickel compounds and presents significant health and environmental hazards, classified as a Category 1A carcinogen with additional reproductive and respiratory sensitization properties.

Nickel(2+) diformate is a solid crystalline compound at room temperature with characteristic properties typical of nickel salts. The substance typically appears as colored crystals, as most nickel(II) compounds exhibit distinctive coloration due to d-electron transitions. Its molecular structure consists of nickel coordinated with formate ligands, contributing to its specific chemical behavior. The compound's solubility and other physical properties depend on environmental conditions such as temperature and pH.

Nickel(2+) diformate is primarily used in specialized industrial applications requiring nickel compounds. It serves as a precursor in catalysis processes, particularly in organic synthesis and chemical manufacturing. The compound may be utilized in electroplating processes, battery manufacturing, and as an intermediate in the production of other nickel-based materials. Its applications are typically restricted to professional industrial settings due to its hazardous classification and regulatory constraints.

Nickel(2+) diformate requires strict safety measures due to its carcinogenic and sensitizing properties. Personal protective equipment must include respiratory protection (P3 filter), chemical-resistant gloves, safety goggles, and protective clothing. Work should be conducted in well-ventilated areas or under fume hoods to prevent inhalation. Direct skin contact must be avoided at all costs. Only trained personnel should handle this substance, following established safety protocols and emergency procedures.

Nickel(2+) diformate must be stored in tightly sealed containers in a cool, dry, well-ventilated area away from incompatible materials. Storage areas should be restricted to authorized personnel only, with appropriate warning signs indicating the carcinogenic nature of the substance. The storage facility must comply with local regulations for hazardous substances. Containers should be properly labeled and protected from physical damage, moisture, and temperature fluctuations to maintain product integrity.

Immediate action is required upon contact with nickel(2+) diformate. For skin contact, remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. In case of eye contact, rinse immediately with clean water for 15 minutes and seek medical attention. If inhaled, move the person to fresh air and seek immediate medical care. For ingestion, do not induce vomiting and seek emergency medical assistance immediately.

Nickel(2+) diformate must be disposed of as hazardous waste through licensed waste management companies specializing in heavy metal compounds. The substance cannot be disposed of in regular waste streams due to its carcinogenic properties and environmental toxicity. Disposal must comply with local and European waste regulations, including proper documentation and tracking. Empty containers may also require special treatment due to potential residual contamination with the hazardous substance.

Nickel(2+) diformate is classified as Class 9 dangerous goods under ADR regulations with Packing Group III designation. Transportation requires appropriate packaging, labeling with GHS08 and GHS09 pictograms, and proper shipping documentation. Vehicles must carry appropriate emergency equipment and drivers need hazardous materials training. The transport must comply with ADR/RID regulations for miscellaneous dangerous substances, including route restrictions and quantity limitations for different transport categories.

Nickel(2+) diformate is subject to comprehensive European chemical regulations including REACH registration requirements and CLP classification obligations. The substance must be classified with multiple hazard categories including Carc. 1A, Muta. 2, and Repr. 1B, requiring specific labeling and safety data sheets. Industrial users must implement appropriate risk management measures and may face restrictions under various chemical safety regulations. Workplace exposure limits and monitoring requirements may apply under occupational health legislation.

Nickel(2+) diformate is available through specialized chemical distributors like OYSI, which serves the European market with professional-grade chemicals. Due to its hazardous classification, purchase is typically restricted to qualified industrial users with appropriate handling capabilities and regulatory compliance. Buyers must provide proper documentation and may need to demonstrate legitimate use and adequate safety measures. OYSI can provide technical support and regulatory guidance for European customers requiring this specialized nickel compound.
