使用1,4-Diiodobenzene is used in Suzuki reaction. It is used as a precursor in the preparation of martinellic acid and 1,4-bis(p-R-phenylethynyl)benzenes. Further, it is employed in the preparation of 1,4-diiodo-2,5-didodecylbenzene , which is a starting reagent for the synthesis of oligo(1,4-phenylene ethynylene). It is also used in human and animal nutrition products including antiseptics and disinfectants. In addition to this, it used in polarizing films for liquid crystal display chemicals.
純化方法Crystallise it from EtOH or boiling MeOH, then dry it in air. [Beilstein 5 IV 700.]
