Copper(I) azide is an inorganic chemical compound with the formula CuN₃. It is composed of a copper cation (Cu⁺) and an azide anion (N−3).

Properties

Copper(I) azide has been used in the preparation of high-energy materials using methods with low environmental cost. These preparations were completed using systems that were high in nitrogen and without any oxygen.^[1] Like most azides, it is explosive.

CuAAC

Copper(I) azide is supported during the process of copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC).^[2]
