Copper (II) Oxide is an inorganic compound with the chemical formula CuO and CAS Number 1317-38-0. It is typically supplied as a black powder or crystalline solid and is practically insoluble in water. It can react with acids to form copper(II) salts and water.

Copper (II) Oxide is valued as a source of copper(II) in chemical reactions and materials research. Common laboratory applications include inorganic chemistry experiments, preparation of copper-containing compounds, oxidation-reduction studies, and investigations involving metal oxides and their chemical properties.

Its properties also make Copper (II) Oxide useful in ceramics research, materials science, and selected catalytic studies. The appropriate grade and purity should be selected according to the requirements of the intended application.

KSFE Malaysia supplies laboratory chemicals and scientific products for research institutions, educational facilities, and general laboratory applications.

Safety Note: Handle Copper (II) Oxide in accordance with the product label and supplier's safety data sheet (SDS). Avoid inhalation of dust and contact with the eyes and skin. Use appropriate personal protective equipment and minimise dust generation during handling. Prevent release into drains or the environment, as copper compounds may be hazardous to aquatic organisms.
