Copper(II) Aspirinate

Copper(II) aspirinate is a coordination compound with the formula C 36 H 28 Cu 2 O 16. Copper aspirinate has been shown to have anti-inflammatory properties and to be a treatment for rheumatoid arthritis, but there are no name brands containing copper aspirinate.

Synthesis
Copper aspirinate can be prepared by reacting aspirin, or acetylsalicylic acid, with dissolved sodium carbonate or sodium bicarbonate to produce sodium aspirinate.

Once this reaction has completed a solution can be made with the sodium aspirinate and a Cu2+ cation such as Copper(II) Sulfate. A bright blue precipitate will form from the reaction, which can then be washed and dried.
