General description

Copper turnings are a form of copper metal that has been specifically cut to have a high surface area. This form of copper is particularly useful because it provides a greater contact area for reagents to interact with which can help speed up reactions and increase yields.
We are committed to bringing you Greener Alternative Products, which adhere to one of the four categories of Greener Alternatives. This product falls under category 12 PAP and aligns with the Green Chemistry Principle of Catalysis. Click here for more information.

Application

Copper turnings are used to synthesize inorganic salts and organometallic complexes and catalysts that can be employed in a variety of synthetic transformations. It is useful in:
  • Synthesis of polynitro[60]fullerene.
  • Copper-catalyzed azide-alkyne Huisgen cycloaddition (click reaction) to synthesize 5-membered heterocycles.
  • Trifluoromethylation of heteroaromatic compounds.
  • Preparation of electrolyte for all-copper hybrid flow batteries.
