Chemical: Copper iodide (CuI)
Copper iodide (CuI) is listed on the EPA's Chemical Data Reporting (CDR) system. Manufacturers and importers of Copper iodide (CuI) are required to report information about their production and use of this chemical to the EPA under the Toxic Substances Control Act (TSCA). (40 eCFR Part 711)
Copper iodide (CuI): Does not have an individual approval but may be used under an appropriate group standard
A skin, eye, nose, and throat irritant; [HSDB] Acute copper poisoning after ingestion can cause liver injury, methemoglobinemia, and hemolytic anemia. Acute renal failure may result, secondary to massive hemoglobinuria. [Goldfrank, p. 1259] A skin and strong eye irritant; Harmful by ingestion; [Alfa Aesar MSDS] See Copper. See Iodine for the TLV of Iodides.
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)
Ionic copper is absorbed from the stomach, duodenum, & jejunum. The initial absorption is about 30%, but the effective net absorption is only about 5% due to excretion of copper into the bile; biliary copper is bound to protein, & this complex is not reabsorbed. Absorption is influenced by a number of factors including the chemical forms of copper: oxides, hydroxides, iodides, glutamates, citrates, & pyrophosphates of copper are readily absorbed, but copper sulfides & other water insoluble salts are poorly absorbed. Copper complexes of some amino acids are easily absorbed, whereas copper porphyrins present in meat are very poorly absorbed. /Soluble copper salts/

SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.
SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.

8 hr Time Weighted Avg (TWA): 1 mg/cu m /Copper dusts and mists, as Cu/
Excursion Limit Recommendation: Excursions in worker exposure levels may exceed 3 times the TLV-TWA for no more than a total of 30 minutes during a work day, and under no circumstances should they exceed 5 times the TLV-TWA, provided that the TLV-TWA is not exceeded. /Copper dusts and mists, as Cu/
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.
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)
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)

用途有機合成試薬や人工降雨剤など幅広い分野で用いられている。
使用Cuprous iodide is used in the preparation of alkynyl imines, which are crucial intermediates for the synthesis of pyrroles and pyrrole heterocycles. It plays a role in the synthesis of BTBT derivatives, specifically benzothieno[3,2-b]benzothiophene, which are semiconductors used in transistors. Beyond its synthetic utility, copper (I) iodide serves as a catalyst for N-arylation of amines and amino acids, facilitating organic reactions. It also has practical applications as an ice-nucleating chemical, a coating in cathode-ray tubes, and as a source of iodine in animal feeds.

使用用途ヨウ化銅は、電子材料や触媒、樹脂改質剤、医薬といった多方面の原料として使用されています。 1. 電子材料 ヨウ化銅は、電子材料の分野では無機P型半導体の材料として知られています。 半導体には、電子が動くN型半導体とホール (電子のぬけた穴) が動くP型半導体の2種類があります。この中でP型半導体は、実際には電子が移動することでホールがあたかも動くとした半導体で、その中で有機と無機の半導体が製作されています。ヨウ化銅は、このうちの無機P型半導体の材料として優れた特性をもつため使用されています。 2. 有機合成試薬 ヨウ化銅は、有機合成化学分野では触媒やヨウ素化試薬として用いられます。 薗頭カップリング、ウルマン反応などをはじめとするクロスカップリング反応において触媒、あるいは助触媒として働きます。また、と同様に、臭化アリールからヨウ化アリールへの変換反応にも用いることができます。ヨウ化アリールは、各種カップリング反応において臭化アリールより高い反応性を示すことから、この変換は産業的にも重要です。
純化方法Cuprous iodide can be freshly prepared by dissolving an appropriate quantity of CuI in boiling saturated aqueous NaI over 30minutes. Pure CuI is obtained by cooling and diluting the solution with water, followed by filtering and washing sequentially with H2O, EtOH, EtOAc, Et2O and pentane, then drying in vacuo for 24hours [Dieter, J Am Chem Soc 107 4679 1985]. Alternatively wash it with H2O, then EtOH and finally with Et2O containing a little iodine. Traces of H2O are best removed first by heating at 110o and then at 400o. Exess of I2 is removed completely at 400o. It dissolves in Et2O if an amine is present to form the amine complex. On heating it becomes red, then black, but changes to white on cooling. It is sparingly soluble in H2O or alkali iodide solutions but readily soluble in NH3 (which absorbs CO) and in cyanide or thiosulfate solutions.
