Cuprous oxide CAS 1317-39-1, with the chemical formula Cu2O, is an oxide of monovalent copper. It is a bright red powdery solid that is almost insoluble in water. It disproportionates into divalent copper and copper elemental in acidic solutions, and gradually oxidizes into black copper oxide in moist air. Copper oxide is mainly used in the production of anti fouling paint for ship bottoms (used to kill low-level marine animals), insecticides, various copper salts, analytical reagents, red glass, and in the preparation of copper plating and copper alloy solutions.
