Iodomethane

Iodomethane is a chemical compound. It is naturally emitted by rice plantations in small amounts. It is used in organic synthesis as a source of methyl groups, and was approved for use as a pesticide in a controversial decision by the United States Environmental Protection Agency in 2007. The primary use of iodomethane is as a chemical intermediate in the manufacture of certain pharmaceuticals and pesticides. It is also used in methylation processes and in the field of microscopy. To a lesser extent, iodomethane has been used in fire extinguishers and as an insect fumigant.

Ionophore

Ionophore is a lipid-soluble molecule usually synthesized by microorganisms to transport ions across the lipid bilayer of the cell membrane. Ionophores disrupt the transmembrane ion concentration gradients required for the proper functioning and survival of microorganisms, and thus have antibiotic properties. In laboratory research, ionophores are used to increase the permeability of biological membranes to certain ions. Ionophores are classified as carboxylic polyether antibiotics, and they disrupt the ion concentration gradient across microorganisms, which cause them to enter a futile ion cycle. Ionophores function by selecting against or negatively affecting the metabolism of gram-positive bacteria and protozoa in the rumen. Ionophores are included in either dry or liquid manufactured supplements, allowing for specific formulations of ionophore concentrations and the option to control intake of the supplement. Ionophores can also be included in loose mineral mixtures, which can be used to limit intake of the mineral. Ionophores have been used to positively affect reproductive processes in the beef cow herd.

Iridium

Iridium is the second-densest element and is the most corrosion-resistant metal. It was discovered in 1803 among insoluble impurities in natural platinum. Smithson Tennant, the primary discoverer, named the iridium for the goddess Iris, personification of the rainbow, because of the striking and diverse colors of its salts. The most important iridium compounds in use are the salts and acids it forms with chlorine, though iridium also forms a number of organometallic compounds used in industrial catalysis, and in research. Iridium metal is employed when high corrosion resistance at high temperatures is needed, as in high-end spark plugs, crucibles for recrystallization of semiconductors at high temperatures, and electrodes for the production of chlorine in the chloralkali process. Iridium radioisotopes are used in some radioisotope thermoelectric generators.

Iridium Carbonyl

Tetrairidium dodecacarbonyl is a chemical compound. This tetrahedral cluster is the most common and most stable "binary" carbonyl of iridium. This air-stable species is only poorly soluble in organic solvents. It has been used to prepare bimetallic clusters and catalysts.

Iridium Trichloride

Iridium Trichloride is the anhydrous compound is relatively rare, but the related hydrate is useful for preparing other iridium compounds.Iridium Trichloride is an excellent water soluble crystalline Iridium source for uses compatible with chlorides.

Iron

Iron is a metal in the first transition series. It is the most common element in the whole planet Earth, forming much of Earth's outer and inner core, and it is the fourth most common element in the Earth's crust. Iron plays an important role in biology, forming complexes with molecular oxygen in hemoglobin and myoglobin; these two compounds are common oxygen transport proteins in vertebrates. It is also used at the active site of many important redox enzymes dealing with cellular respiration and oxidation and reduction in plants and animals. Iron is the most widely used of all the metals. It is used for the construction of machinery and machine tools, automobiles, the hulls of large ships, and structural components for buildings. Since pure iron is quite soft, it is most commonly used in the form of steel. Iron catalysts are traditionally used in the Haber-Bosch Process for the production of ammonia and the Fischer-Tropsch process for conversion of carbon monoxide to hydrocarbons for fuels and lubricants. Powdered iron in an acidic solvent was used in the Bechamp reduction the reduction of nitrobenzene to aniline. Iron(III) chloride finds use in water purification and sewage treatment, in the dyeing of cloth, as a coloring agent in paints, as an additive in animal feed, and as an etchant for copper in the manufacture of printed circuit boards. Iron(II) sulfate is used as a precursor to other iron compounds. It is also used to reduce chromate in cement. It is also used to fortify foods and treat iron deficiency anemia.

Iron Nonacarbonyl

Diiron nonacarbonyl is an inorganic compound. This metal carbonyl is an important reagent in organometallic chemistry and of occasional use in organic synthesis. It is a more reactive source of Fe(0) than Fe(CO)5 and less dangerous to handle because it is nonvolatile. This micaceous orange solid is virtually insoluble in all common solvents.

Iron powder

Iron Powder is powdered iron. Iron powder is formed as a whole from several other iron particles. Most iron powders are used for automobile parts.
