Toxicology
Treatment
EYES: irrigate opened eyes for several minutes under running water. INGESTION: do not induce vomiting. Rinse mouth with water (never give anything by mouth to an unconscious person). Seek immediate medical advice. SKIN: should be treated immediately by rinsing the affected parts in cold running water for at least 15 minutes, followed by thorough washing with soap and water. If necessary, the person should shower and change contaminated clothing and shoes, and then must seek medical attention. INHALATION: supply fresh air. If required provide artificial respiration.
Chemistry & industry
Pharmacology
Metabolism/Metabolites
Copper is mainly absorbed through the gastrointestinal tract, but it can also be inhalated and absorbed dermally. It passes through the basolateral membrane, possibly via regulatory copper transporters, and is transported to the liver and kidney bound to serum albumin. The liver is the critical organ for copper homoeostasis. In the liver and other tissues, copper is stored bound to metallothionein, amino acids, and in association with copper-dependent enzymes, then partitioned for excretion through the bile or incorporation into intra- and extracellular proteins. The transport of copper to the peripheral tissues is accomplished through the plasma attached to serum albumin, ceruloplasmin or low-molecular-weight complexes. Copper may induce the production of metallothionein and ceruloplasmin. The membrane-bound copper transporting adenosine triphosphatase (Cu-ATPase) transports copper ions into and out of cells. Physiologically normal levels of copper in the body are held constant by alterations in the rate and amount of copper absorption, compartmental distribution, and excretion. (L277, L279)

Applications
UsesCopper(II) fluoride is used in cathodes in nonaqueous galvanic cells, such as high energy batteries. It also is used as a fluorinating agent. The dihydrate is used in welding and brazing fluxes and is added to cast iron to improve its strength. Another application of this compound is as opacifier in ceramics, glasses and enamels.
UsesCeramics, enamels, flux in metallurgy, highenergy batteries, fluorinating agent.
UsesCathodes in nonaqueous galvanic cells, high temp. fluorinating agent.Copper(II) fluoride is used in the preparation of fluorobenzene by reacting with benzene. It is also used in galvanic cells, high-temperature fluorinating agent and fluxing iron castings. Further, it is used as an efficient catalyst in Chan-Lam-Evans coupling reaction to synthesis the diaryl- ether compounds.
