Overview

Nickel(2+) oxalate (CAS 547-67-1) is an inorganic nickel salt compound with crystalline structure and significant toxicological properties requiring careful handling protocols. This nickel-based chemical compound represents an important industrial intermediate in various manufacturing processes, particularly where controlled nickel content is essential. The substance exhibits the characteristic properties of transition metal oxalates, forming stable crystalline structures that make it valuable in specialized applications. With its molecular formula C2NiO4 and molar mass of 146.71 g/mol, nickel(2+) oxalate demonstrates predictable stoichiometric behavior in chemical reactions. The compound carries significant safety considerations due to its classification as a Category 1A carcinogen and respiratory sensitizer. Its hazard profile includes potential for causing allergic skin reactions and acute aquatic toxicity, necessitating stringent handling procedures and environmental protection measures. The GHS08, GHS07, and GHS09 pictograms reflect these serious health and environmental hazards, while its ADR Class 9 classification affects transportation requirements. Industrial applications typically include use as a precursor in the synthesis of nickel-containing catalysts, where controlled decomposition produces highly active nickel surfaces. The compound also finds application in electroplating processes and specialized metallurgical operations. In the broader context of nickel compounds, it shares certain applications with related materials such as sulfanylidenenickel, though each exhibits distinct properties suited to specific industrial requirements. OYSI maintains technical-grade nickel(2+) oxalate availability for qualified industrial customers, supporting European chemical manufacturing operations with comprehensive documentation and regulatory compliance assistance.
