Zinc-copper couple is used in the Simmons-Smith cyclopropanation reaction, Reformatsky reaction. It is used as a chemical for the selective, stereospecific reduction of alkynes to cis-alkenes. It is used in for deiodination of iodotributylstannylalkanes. In the presence of a free-radical initiator, it promotes the formylation of perfluoroalkyl iodides with DMF to give fluorinated aldehydes in high yield. It is used in dermatology.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
