Cobalt 2-Ethylhexanoate is a Cobalt source that is soluble in organic solvents as an organometallic compound (also known as metalorganic, organo-inorganic and metallo-organic Organo-Metallic Packaging, Lab Quantity compounds). Ethylhexanoates are carboxylates with many commercial applications. They are commonly used in various catalysts for oxidation, hydrogenation and polymerization and as an adhesion promoter. It is generally immediately available in most volumes. Ultra high purity and high purity forms may be considered. Cobalt 2-Ethylhexanoate is one of numerous organo-metallic compounds (also known as metalorganic, organo-inorganic and metallo-organic compounds) sold by American Elements under the tradename AE Organo-Metallics™ for uses requiring non-aqueous solubility such as recent solar energy and water treatment applications. Similar results can sometimes also be achieved with Nanoparticles and by thin film deposition. Note American Elements additionally supplies many materials as solutions. American Elements produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia) and follows applicable ASTM testing standards. Typical and custom packaging is available. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.

Cobalt (Co) atomic and molecular weight, atomic number and elemental symbolCobalt (atomic symbol: Co, atomic number: 27) is a Block D, Group 9, Period 4 element with an atomic weight of 58.933195. Cobalt Bohr Model The number of electrons in each of cobalt's shells is 2, 8, 15, 2 and its electron configuration is [Ar] 3d7 4s2The cobalt atom has a radius of 125 pm and a Van der Waals radius of 192 pm. Cobalt was first discovered by George Brandt in 1732. In its elemental form, cobalt has a lustrous gray appearance. Cobalt is found in cobaltite, erythrite, glaucodot and skutterudite ores. Elemental Cobalt Cobalt produces brilliant blue pigments which have been used since ancient times to color paint and glass. Cobalt is a ferromagnetic metal and is used primarily in the production of magnetic and high-strength superalloys. Co-60, a commercially important radioisotope, is useful as a radioactive tracer and gamma ray source. The origin of the word Cobalt comes from the German word "Kobalt" or "Kobold," which translates as "goblin," "elf" or "evil spirit."
