Copper;oxocopper

Copper;oxocopper is cuprous oxide (Cu2O), an inorganic compound consisting of copper in its +1 oxidation state. This red to reddish-brown crystalline solid occurs naturally as the mineral cuprite and serves as an important copper compound in various industrial applications. With a molecular weight of 143.09 g/mol, it represents one of the primary oxides of copper and exhibits semiconducting properties.

Copper;oxocopper appears as a red to reddish-brown crystalline solid with no characteristic odor. It has a density of approximately 6.0 g/cm³ and melts at around 1,235°C. The compound is practically insoluble in water but dissolves in acids and ammonia solutions. It exhibits semiconducting properties and can undergo disproportionation reactions under certain conditions to form metallic copper and copper(II) compounds.

Copper;oxocopper serves multiple industrial purposes including use as a semiconductor material in electronic applications, as a catalyst in organic synthesis reactions, and as a pigment in ceramics and glass manufacturing. It functions as an antifouling agent in marine paints, a fungicide in agricultural applications, and a precursor for other copper compounds. Additionally, it finds application in solar cell technology and as a reducing agent in various chemical processes.

Copper;oxocopper requires careful handling due to its Acute Tox. 4 and Eye Dam. 1 classifications. Personnel must wear appropriate personal protective equipment including safety goggles, gloves, and respiratory protection to prevent inhalation of dust. Work in well-ventilated areas or under local exhaust ventilation. Avoid contact with skin, eyes, and clothing. Wash hands thoroughly after handling and do not eat, drink, or smoke while working with this material.

Copper;oxocopper should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from incompatible materials such as strong acids, alkalis, and reducing agents. Keep containers upright and properly labeled according to GHS requirements. Store away from heat sources, direct sunlight, and moisture. Ensure storage areas have appropriate spill containment measures due to its aquatic toxicity classification. Regular container inspection is recommended to prevent deterioration.

In case of eye contact with copper;oxocopper, immediately flush with plenty of water for at least 15 minutes and seek medical attention due to its Eye Dam. 1 classification. For skin contact, wash thoroughly with soap and water. If inhaled, move to fresh air immediately and seek medical attention if symptoms persist. In case of ingestion, rinse mouth and drink water, but do not induce vomiting. Always consult a physician and provide the safety data sheet.

Copper;oxocopper waste must be disposed of according to local, national, and international regulations due to its hazardous classification and aquatic toxicity. It cannot be disposed of in regular waste streams and requires handling by licensed waste management companies. Recovery and recycling of copper content is often preferred from both environmental and economic perspectives. Prevent release to sewers, waterways, or soil due to its Aquatic Acute 1 and Aquatic Chronic 1 classifications.

Copper;oxocopper is classified as ADR Class 9 (Miscellaneous dangerous goods), Packing Group III for transport purposes. It requires appropriate packaging, labeling, and documentation according to dangerous goods regulations. Transport vehicles must carry proper placarding and emergency response information. Drivers need ADR certification for dangerous goods transport. The compound must be secured to prevent movement during transit and protected from moisture and damage to packaging integrity.

Copper;oxocopper is subject to various European regulations including REACH registration requirements, CLP classification and labeling obligations, and potential restrictions under REACH Annex XVII. It is not currently listed as a Substance of Very High Concern (SVHC). Companies must comply with occupational exposure limits, environmental discharge regulations, and waste management directives. Import/export may require additional documentation depending on destination countries and quantities involved.
