Applications

Copper(II) pyrophosphate hydrate is used in printed circuit boards. It catalyzes the dimerization of isobutylene to diisobutylene. It is involved in the electrodeposition of copper-zinc alloys based electrolytes. Further, it is used in animal feed as a supplement. In addition to this, it is used in plating of copper on plastics, aluminum, and zinc.

Notes

Incompatible with strong oxidizing agents.
