Ethylferrocene is an organoiron compound with the formula Fe(C5H5)C5H4C2H5). It is a derivative of ferrocene containing an ethyl group on one of the two cyclopentadienyl rings. Relative to the properties of ferrocene, its melting point is lower and its solubility of the compound in hydrocarbon solvents is improved.
