One of the important herbicide , for investigation of practical mechanism and studies of metabolism function of different plant, is the 2,4 dichlorophenoxy acetic acid compound .In this article, the production method of its labeled the title compound is explained. In the first step barium [ 14C]carbonate  is converted into potassium [ 14C]cyanide, by using potassium azid at reasonable temperature. Then , after a few synthsis reaction, the compound “ 2,4 dichlorophenoxy methyl iodide is produced via 2,4 dichlorophenoxy, as a starting material. In the next step, the real material as a herbicide: 2,4 dichlorophenoxy acetic acid [carboxy- 14C] is prepared and produced, by coupling reaction  between 2,4 dichlorophenoxy methyl iodide and potassium [ 14C]cyanide , and then hydrolized the resulting nitrile.
