Copper;oxocopper

Copper;oxocopper is cuprous oxide (Cu2O), an inorganic compound consisting of copper in its +1 oxidation state. This red-brown crystalline solid has a molecular weight of 143.09 g/mol and CAS number 1317-39-1. It occurs naturally as the mineral cuprite and is widely used in industrial applications. The compound is classified as hazardous with acute toxicity, eye damage potential, and environmental toxicity properties, requiring careful handling and storage protocols.

Copper;oxocopper appears as a red to reddish-brown crystalline powder or solid with no distinctive odor. It has limited solubility in water but dissolves in acidic solutions and ammonia. The compound is stable under normal conditions but can oxidize to copper(II) oxide when exposed to air at elevated temperatures. It exhibits semiconductor properties and has a cubic crystal structure. These physical characteristics make it suitable for various industrial applications while requiring specific handling considerations.

Copper;oxocopper serves multiple industrial purposes including use as a pigment in ceramics, glass, and paints to produce red coloration. It functions as an antifouling agent in marine paints, a fungicide in agriculture, and a catalyst in organic synthesis reactions. The compound is also utilized in electronics as a semiconductor material and in the production of other copper compounds. Its antimicrobial properties make it valuable in wood preservation and certain medical applications.

Copper;oxocopper requires careful handling due to its Acute Tox. 4 and Eye Dam. 1 classifications. Wear appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and respiratory protection to prevent inhalation. Work in well-ventilated areas or under fume extraction systems. Avoid generating dust and prevent skin and eye contact. Wash hands thoroughly after handling and do not eat, drink, or smoke in work areas. Emergency eyewash and shower facilities should be readily accessible.

Copper;oxocopper should be stored in tightly sealed, original containers in a cool, dry, well-ventilated area away from direct sunlight and heat sources. Keep separate from incompatible materials such as strong acids, oxidizing agents, and aluminum. Store away from water sources due to its environmental hazard classification (Aquatic Acute 1, Aquatic Chronic 1). Ensure storage areas have appropriate spill containment measures and restrict access to authorized personnel only.

Immediate action is required for copper;oxocopper contact due to its hazardous properties. For eye contact, rinse immediately with plenty of clean water for at least 15 minutes and seek medical attention urgently due to Eye Dam. 1 classification. For skin contact, wash thoroughly with soap and water. If inhaled, move to fresh air immediately. In case of ingestion, rinse mouth and seek medical advice. Do not induce vomiting. Always seek professional medical attention for any exposure incident.

Copper;oxocopper disposal must comply with local and national hazardous waste regulations due to its environmental toxicity classification. The compound cannot be disposed of in regular waste streams and requires specialized hazardous waste treatment. Contact licensed waste disposal companies for proper collection and treatment. Small quantities should be collected in appropriate containers and labeled clearly. Prevent release to water bodies, sewers, or soil due to its aquatic toxicity. Maintain disposal records as required by regulations.

Copper;oxocopper is classified as ADR Class 9 (Miscellaneous Dangerous Goods), Packing Group III, requiring compliance with dangerous goods transport regulations. Use approved packaging materials and ensure proper labeling with hazard identification numbers and emergency contact information. Transport vehicles must carry appropriate documentation including safety data sheets and emergency response procedures. Drivers require ADR certification for dangerous goods transport. Avoid transport during extreme weather conditions and ensure secure loading to prevent spillage.

Copper;oxocopper is subject to multiple regulatory frameworks including REACH registration requirements in Europe and CLP classification obligations. Its hazard classification (Acute Tox. 4, Eye Dam. 1, Aquatic toxicity) triggers specific labeling, packaging, and safety data sheet requirements. Although not currently listed as SVHC, it requires notification under poison center regulations due to its toxicity. Industrial users must comply with occupational exposure limits and environmental discharge restrictions under various national and EU directives.
