Used as a catalyst in organic synthesis, particularly in coupling reactions such as Ullmann and Glaser reactions, enabling carbon-carbon bond formation.

Employed in electroplating solutions to deposit copper coatings on various substrates for improved conductivity and corrosion resistance.

Serves as a wood preservative due to its antimicrobial and antifungal properties, protecting against decay and insect damage.

Utilized in textile dyeing as a mordant to fix dyes on fabrics, enhancing color fastness.

Applied in agriculture as a component of fungicides and micronutrient supplements for copper-deficient soils, particularly for grapes and certain vegetables due to its inhibitory effect on fungal growth.

Used in the paint and coating industry for its blue-green pigmentation, suitable for artistic works, murals, and wood finishes.

Also employed in laboratory research to study transition metal properties and as a starting material for synthesizing other copper-based compounds.
