Question? Ask an American Elements Materials Science Engineer
Ferrocene (also known as Bis(cyclopentadienyl)iron) is an organometallic iron complex known as a metallocene, consisting of an iron atom sandwiched between two cyclopentadienyl rings. Ferrocene is a versatile compound that can serve as a precursor material for numerous types of organic compounds, a fuel additive, and a source of iron nanoparticles for the production of carbon nanotubes. HAmerican 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. Additional technical, research and safety (MSDS) information is available. Please request a quote above to receive pricing information based on your specifications.

See more Iron products. Iron (atomic symbol: Fe, atomic number: 26) is a Block D, Group 8, Period 4 element with an atomic weight of 55.845. The number of electrons in each of Iron's shells is 2, 8, 14, 2 and its electron configuration is [Ar] 3d6 4s2. 
The iron atom has a radius of 126 pm and a Van der Waals radius of 194 pm. Iron was discovered by humans before 5000 BC. In its elemental form, iron has a lustrous grayish metallic appearance. Iron is the fourth most common element in the Earth's crust and the most common element by mass forming the earth as a whole. Iron is rarely found as a free element, since it tends to oxidize easily; it is usually found in minerals such as magnetite, hematite, goethite, limonite, or siderite.
Though pure iron is typically soft, the addition of carbon creates the alloy known as steel, which is significantly stronger.
