Copper(II) acetylsalicylate, or copper aspirinate, as it is sometimes called, is a compound of copper and acetylsalicylic acid (aspirin). It is a blue solid with the formula Cu2C36H28O16.

Properties

Chemical

This little-known compound is a chelating agent that shows promise as a drug for rheumatoid arthritis.

Physical

Copper aspirinate is a richly colored blue solid that is insoluble in water and organic solvents.

Availability

Copper(II) acetylsalicylate is produced in the lab, rather than obtained elsewhere.

Preparation

Copper(II) acetylsalicylate can be produced by the combination of solutions containing a copper(II) salt and sodium acetylsalicylate in a 1-to-2 molar ratio, respectively.

Projects

Copper aspirinate may be usable as a blue pigment for various projects. It is also an intriguing specimen to add to a copper compounds collection.

Handling

Safety

Copper aspirinate does not demonstrate the toxicity of most copper(II) compounds. However, lab grade material should never be ingested. Additionally, large amounts of salicylate can cause a serious medical condition, salicylism.

Storage

Copper aspirinate should be stored in closed containers, be it plastic or glass. Avoid metal containers, like steel cans.

Disposal

Copper aspirinate can be mixed with a flammable solvent and safely burned. It can also be neutralized with Fenton's reagent if needed.

The resulting copper wastes should be recycled.
