Acts as a catalyst in organic synthesis and in the removal of sulfur from petroleum products.

Employed in the production of batteries, especially in lithium-ion and alkaline types, and in semiconductor materials due to its electrochemical and electrical properties.

Utilized in antimicrobial, antifungal, and antibacterial coatings, textiles, construction materials, and paints because of its ability to inhibit bacterial and fungal growth.

Applied in the synthesis of superconductors and in the manufacturing of wood preservatives.

Also used in the preparation of other copper salts, in metallurgical processes as a flux component, as a trace additive in fertilizers and animal feed to supplement copper, and in laboratory chemical analysis and organic synthesis as a copper source.
