Copper(II) aspirinate is an aspirin chelate of copper(II) cations (). It is a bright blue solid, forming monoclinic crystals.
Preparation Copper aspirinate can be prepared treating a solution of aspirin and potassium bicarbonate with copper(II) sulfate solution.
Heating an equimolar mixture of aspirin and copper salicylate tetrahydrate in 50% aqueous ethanol results in dark blue crystals.
Research Copper aspirinate has been investigated for its claimed anti-inflammatory, antioxidative, and antithrombotic properties as well as a potential treatment for skin disorders.
The use of copper aspirinate as a pigment in PVC and polystyrene has also been investigated.
