Widely used as a versatile source of copper(I) in catalytic reactions, especially in organic synthesis. It plays a key role in coupling reactions such as C–N, C–O, and C–S bond formations, offering high efficiency and selectivity. Commonly employed in click chemistry, particularly in azide-alkyne cycloadditions, due to its ability to generate active copper species in situ. Its acetonitrile ligands are labile, allowing easy substitution by other ligands or substrates, making it ideal for homogeneous catalysis. Also utilized in materials science for the preparation of copper-containing complexes and coordination polymers. The compound is valued for its solubility in polar organic solvents, which facilitates its use in a wide range of reaction conditions.
