|  |  | 1,4-Dichloro-2-butyne Usage And Synthesis | 
 | Chemical Properties | CLEAR COLORLESS TO YELLOWISH LIQUID |  | Uses | 1,4-Dichloro-2-butyne used in the synthesis of 1,4-disubstituted 1,2,3-triazoles. Also, it is used in the approach of the 20S-camptothecin family of antitumor agents. |  | Safety Profile | Poison by intravenous 
route. When heated to decomposition it 
emits toxic fumes of Cl-. Probably a 
dangerous fKe and explosion hazard. See
