| Overview | The structure of 1,5-difluoro-2, 4-dinitrobenzene contains two nitro groups and two fluorine groups. The nitro group is an energetic group, and the fluorine group can be further modified into other energetic groups, so 1, 5-difluoro-2, 4-Dinitrobenzene is also an intermediate that can be widely used in the field of energetic materials. |
| Use | 1, 5-difluoro-2, 4-dinitrobenzene is an important intermediate for the synthesis of the herbicide propargumine. It can be treated by etherification, hydrogenation reduction of the ring, and reaction with bromopine and anhydride in turn to obtain propargumine. |
