Copper acetate (usually referred to as copper acetate monohydrate, chemical formula Cu (CH3 COO) ₂ · H ₂ O) is an important copper salt widely used in industries, agriculture, medicine, and scientific research. According to the latest publicly available information (as of 2026), its main applications are as follows:
Organic synthesis catalyst
Copper acetate is an efficient catalyst or oxidant for various organic reactions, such as:
Catalytic coupling of terminal alkynes to generate 1,3-diynes;
Used for synthesizing complex molecules such as alkynes, cyclopropane derivatives, α, β - unsaturated sulfones, etc;
Plays a critical role in reactions such as C-H bond activation, allyl oxidation, and carbon metal bond cleavage
Agriculture and Plant Protection
As a fungicide, it has significant effects on cucumber bacterial leaf spot disease, eggplant red spot disease, apple tree rot disease, grape downy mildew, etc
Used as an algaecide, for water purification, and to inhibit excessive growth of algae
It is one of the important raw materials for preparing Bordeaux mixture (a mixture of copper sulfate and lime)
Coatings and Printing and Dyeing
Used as a quick drying agent for paint to accelerate coating drying
As a raw material for porcelain glaze pigments, it provides green or blue tones
Used as a fixative or mordant in printing and dyeing to enhance dye adhesion
Wood anti-corrosion and mildew prevention
Utilizing the antibacterial properties of copper ions in wood preservative formulations to prevent decay by fungi and insects
It can also be added to textiles and paper to achieve anti mold function
Electrochemistry and Electronic Materials
As an electrolyte component in copper electroplating process, used for copper layer deposition on printed circuit boards (PCBs)
Used for preparing conductive pastes and copper interconnect material precursors, with potential applications in semiconductor manufacturing
