Infobox disclaimer and references

FOX-7 or 1,1-diamino-2,2-dinitroethylene is an insensitive high power explosive compound. It was first synthesized in 1998 by the FOA Defence Research Establishment (Sweden). [1]

FOX-7 is similar to the insensitive chemical compound TATB, which is a benzene ring compound with three amino and three nitro groups. FOX-7 has a linear two-carbon backbone rather than a benzene ring, but the amino and nitro groups have similar effects in both cases according to published reports on sensitivity and chemical decay processes of FOX-7.

Its explosive properties appear extremely favorable; in addition to its insensitive properties, the detonation velocity of mixtures of 80% FOX-7 plus binders are as high as Composition B, and nearly pure FOX-7 based plastic bonded explosives are slightly superior to RDX. [2] FOX-7 has been calculated to have a detonation velocity of 8,870 m/s.[1]

The cost of FOX-7 is relatively high, and it is not known to be found in any production use to date.
