Iodobenzene is an organic compound with the chemical formula C6H5I. It consists of a benzene ring, which is a six-carbon aromatic structure, with an iodine atom attached. This compound is typically a colorless to pale yellow liquid and is used in various chemical reactions, particularly in organic synthesis. Iodobenzene is important in the production of phenols and anilines, as well as in the synthesis of iodinated compounds. It can be produced through the iodination of benzene using iodine and a catalyst, such as iron(III) iodide. Its properties make it useful in pharmaceuticals and agrochemicals.
