Cupric oxalate(CAS: 5893-66-3)

Cupric oxalate (CAS: 5893-66-3) is a white crystalline compound with a molecular weight of approximately 213.51 g/mol. It has a low solubility in water (0.035 g/L at 20°C) and exhibits limited reactivity under normal conditions. It is stable in air and light but may decompose upon heating above 180°C.

Cupric oxalate can be synthesized by dissolving copper(II) sulfate in oxalic acid. The reaction is exothermic and typically carried out in a water bath to control temperature. The product is usually filtered, washed, and dried to obtain the desired crystalline form.

Cupric oxalate finds applications in various industries, including the production of copper-based pigments, electroplating baths, and as a component in analytical reagents. It is also used in the synthesis of other copper compounds and in some pharmaceuticals.

When handling cupric oxalate, it is important to wear protective gloves, safety goggles, and a lab coat to prevent skin and eye contact. It should be stored in a cool, dry place away from direct sunlight. In case of spillage, neutralize with a suitable base and dispose of according to local regulations. Always refer to the Safety Data Sheet (SDS) for detailed handling and storage instructions.
