[140], Organozinc chemistry is the science of compounds that contain carbon-zinc bonds, describing the physical properties, synthesis, and chemical reactions. Zinc is added to the soil primarily through the weathering of rocks, but humans have added zinc through fossil fuel combustion, mine waste, phosphate fertilizers, pesticide (zinc phosphide), limestone, manure, sewage sludge, and particles from galvanized surfaces. [83], William Champion's brother, John, patented a process in 1758 for calcining zinc sulfide into an oxide usable in the retort process. For infants up to 12 months the RDA is 3 mg/day. [107] These properties make it useful in communication equipment, hardware, musical instruments, and water valves. [18] The semiconductor properties of zinc oxide make it useful in varistors and photocopying products. [215], Nearly two billion people in the developing world are deficient in zinc. Skin Contact Wash off immediately with plenty of water for at least 15 minutes. [203], The U.S. Institute of Medicine (IOM) updated Estimated Average Requirements (EARs) and Recommended Dietary Allowances (RDAs) for zinc in 2001.

[114], A widely used zinc alloy is brass, in which copper is alloyed with anywhere from 3% to 45% zinc, depending upon the type of brass. Personal precautions, protective equipment and emergency proceduresNot required.Environmental precautions:Do not allow material to be released to the environment without official permits.Methods and materials for containment and cleanup:Pick up mechanically.Prevention of secondary hazards:No special measures required.Reference to other sectionsSee Section 7 for information on safe handlingSee Section 8 for information on personal protection equipment.See Section 13 for disposal information. [149], In most single-tablet, over-the-counter, daily vitamin and mineral supplements, zinc is included in such forms as zinc oxide, zinc acetate, or zinc gluconate. Shiny grayish-blue irregular granules or lumps. This helps to create a hydrophobic pocket on the enzyme near the zinc, which attracts the non-polar part of the protein being digested. 215503. mossy, 99.99% trace metals basis. [175], Roughly 2–4 grams of zinc[176] are distributed throughout the human body. It was first reported in 1848 from the reaction of zinc and ethyl iodide, and was the first compound known to contain a metal–carbon sigma bond. Each of the nine or ten Zn2+ ions in a zinc finger helps maintain the finger's structure by coordinately binding to four amino acids in the transcription factor. The name zinc originates from the German word "zin," meaning tin. Zinc ores were used to make the zinc–copper alloy brass thousands of years prior to the discovery of zinc as a separate element. 1907/2006.Substance is not listed.The conditions of restrictions according to Article 67 and Annex XVII of the Regulation (EC) No 1907/2006 (REACH) for the manufacturing, placing on the market and use must be observed.Substance is not listed.Annex XIV of the REACH Regulations (requiring Authorisation for use)Substance is not listed.Chemical safety assessment:A Chemical Safety Assessment has not been carried out. Molecular Weight: 65.39. [186], The European Food Safety Authority (EFSA) refers to the collective set of information as Dietary Reference Values, with Population Reference Intake (PRI) instead of RDA, and Average Requirement instead of EAR. [68], German chemist Andreas Marggraf normally gets credit for discovering pure metallic zinc, even though Swedish chemist Anton von Swab had distilled zinc from calamine four years previously. [12] These alloys are marketed under the name Zamak. [57] Zinc deficiency has been associated with major depressive disorder (MDD), and zinc supplements may be an effective treatment. Component Weight % CAS # EINECS# / ELINCS# Formula Molecular Weight Zinc 100 7440-66-6 N/A Zn 65.39 g/mol 4. It is the 24th most abundant element in the earth's crust and the fourth most common metal in use (after iron, aluminum, and copper). Zinc is mined from sulfidic ore deposits. [126] The zinc zinc-oxide cycle is a two step thermochemical process based on zinc and zinc oxide for hydrogen production. These PRIs are higher than the U.S. [21] In Britain, John Lane is said to have carried out experiments to smelt zinc, probably at Landore, prior to his bankruptcy in 1726. China produced 38% of the global zinc output in 2014. [52], Cobalticyanide paper (Rinnmann's test for Zn) can be used as a chemical indicator for zinc. [169][182][170] Dysregulation of zinc homeostasis in the central nervous system that results in excessive synaptic zinc concentrations is believed to induce neurotoxicity through mitochondrial oxidative stress (e.g., by disrupting certain enzymes involved in the electron transport chain, including complex I, complex III, and α-ketoglutarate dehydrogenase), the dysregulation of calcium homeostasis, glutamatergic neuronal excitotoxicity, and interference with intraneuronal signal transduction. [107][note 2] Zinc is also used to cathodically protect metals that are exposed to sea water.

COPYRIGHT 1997-2018 AMERICAN ELEMENTS. [107] Zinc acts as the anode (negative terminus) by slowly corroding away as it passes electric current to the steel pipeline. At least 15 clinical trials have shown that zinc improved weight gain in anorexia. [204] These considerations must be balanced against the paucity of adequate zinc biomarkers, and the most widely used indicator, plasma zinc, has poor sensitivity and specificity. [230], The U.S. Food and Drug Administration (FDA) states that zinc damages nerve receptors in the nose, causing anosmia. [156][157] The intranasal use of zinc-containing nasal sprays has been associated with the loss of the sense of smell;[156] consequently, in June 2009, the United States Food and Drug Administration (USFDA) warned consumers to stop using intranasal zinc. [106] Similarly, a zinc plug attached to a propeller or the metal protective guard for the keel of the ship provides temporary protection. [98] The dumps of the past mining operations leach zinc and cadmium, and the sediments of the Geul River contain non-trivial amounts of metals. Molecular Formula: Zn: Formula Weight: 65.39: Assay (Zn) Min. Buy Zinc Metal Mossy ACS, Zinc Lab Supply, CAS 7440-66-6, and a wide selection of zinc metal available in many proofs, grades, and package sizes for companies in academia/education, food, fragrance, biotech, life science, pharmaceutical, R&D and analytical … Search results for Zn at Sigma-Aldrich. Zinc (atomic symbol: Zn, atomic number: 30) is a Block D, Group 12, Period 4 element with an atomic weight of 65.38. In 2009 in the United States, 55% or 893,000 tons of the zinc metal was used for galvanization. [21] Another estimate gives a total production of 60,000 tonnes of metallic zinc over this period. [68] American Elements shall not be held liable for any damage resulting from handling or from contact with the above product. [57], Chelated zinc is used in toothpastes and mouthwashes to prevent bad breath; zinc citrate helps reduce the build-up of calculus (tartar). A meta-analysis of 33 prospective intervention trials regarding zinc supplementation and its effects on the growth of children in many countries showed that zinc supplementation alone had a statistically significant effect on linear growth and body weight gain, indicating that other deficiencies that may have been present were not responsible for growth retardation. [224], Zinc deficiency appears to be the most common micronutrient deficiency in crop plants; it is particularly common in high-pH soils. [134] When a compressed mixture of 70% zinc and 30% sulfur powder is ignited there is a violent chemical reaction. For people ages 18 and older the PRI calculations are complex, as the EFSA has set higher and higher values as the phytate content of the diet increases. The RDAs are 8 and 11 mg/day. Stomach acid contains hydrochloric acid, in which metallic zinc dissolves readily to give corrosive zinc chloride. The low working temperature leads to rapid cooling of the cast products and fast production for assembly.

[200][201][202] The human serotonin transporter and norepinephrine transporter do not contain zinc binding sites. [139] Zinc in the form of ZDDP, is used as an anti-wear additive for metal parts in engine oil. Molecular Formula Zn; Average mass 65.409 Da; Monoisotopic mass 63.929146 Da; ChemSpider ID 22430 [137], Zinc dithiocarbamate complexes are used as agricultural fungicides; these include Zineb, Metiram, Propineb and Ziram. [131] Crystals of ZnS are used in lasers that operate in the mid-infrared part of the spectrum. Zinc. The concentration of zinc in plants varies with the level in the soil. Safety Data Sheet according to Regulation (EC) No. The above information is believed to be correct but does not purport to be all inclusive and shall be used only as a guide. The smelting of metallic zinc here, however, appears to have begun around the 12th century AD.
