Overview

Copper(II) fluoride is a fluoride of copper. Copper is a chemical element with the symbol Cu and atomic number 29. Copper is an essential elements in plants and animals as it is required for the normal functioning of more than 30 enzymes. It occurs naturally throughout the environment in rocks, soil, water, and air. (L277, L278)

Toxicology

Treatment · 1 item

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.

Health Effects · 1 item

People must absorb small amounts of copper every day because copper is essential for good health, however, high levels of copper can be harmful. Very-high doses of copper can cause damage to your liver and kidneys, and can even cause death. Copper may induce allergic responses in sensitive individuals. (L278, L279)

Exposure RoutesOral (L277) ; inhalation (L277) ; dermal (L277)
Toxicity Summary · 1 item

Excess copper is sequestered within hepatocyte lysosomes, where it is complexed with metallothionein. Copper hepatotoxicity is believed to occur when the lysosomes become saturated and copper accumulates in the nucleus, causing nuclear damage. This damage is possibly a result of oxidative damage, including lipid peroxidation. Copper inhibits the sulfhydryl group enzymes such as glucose-6-phosphate 1-dehydrogenase, glutathione reductase, and paraoxonases, which protect the cell from free oxygen radicals. It also influences gene expression and is a co-factor for oxidative enzymes such as cytochrome C oxidase and lysyl oxidase. In addition, the oxidative stress induced by copper is thought to activate acid sphingomyelinase, which lead to the production of ceramide, an apoptotic signal, as well as cause hemolytic anemia. Copper-induced emesis results from stimulation of the vagus nerve. (L277, T49, A174, L280)

Pharmacology

Metabolism/Metabolites · 1 item

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 · 4 items

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.

General DescriptionCopper fluoride is a monoclinic weak ferromagnet. The structural properties were investigated by neutron diffraction.

PreparationCopper(II) fluoride is prepared by direct fluorination of copper at high temperatures: Cu + F2 → CuF2 It also may be prepared by passing hydrogen fluoride gas over copper(II) oxide at 400°C: CuO + 2HF→ CuF2 + H2O Alternatively, it may be made by treating copper carbonate with hydrofluoric acid followed by crystallization. CuCO3 + 2HF(aq) → CuF2 + H2O + CO2

DefinitionThe anhydrous form, CuF2, is also available.
