Descriptions:
pubchem: Octogen is a tetrazocane that is 1,3,5,7-tetrazocane in which the hydrogen atom attached to each of the nitrogens is replaced by a nitro group. It has a role as an explosive. It is a N-nitro compound and a tetrazocane.
chebi: A tetrazocane that is 1,3,5,7-tetrazocane in which the hydrogen atom attached to each of the nitrogens is replaced by a nitro group.
wikipedia: HMX, also called octogen, is a powerful and relatively insensitive nitroamine high explosive chemically related to RDX. The compound's name is the subject of much speculation, having been variously listed as High Melting Explosive, High-velocity Military Explosive, or High-Molecular-weight RDX, as well as Her Majesty's Explosive.
The molecular structure of HMX consists of an eight-membered ring of alternating carbon and nitrogen atoms, with a nitro group attached to each nitrogen atom. Because of its high mass-specific enthalpy of formation, it is one of the most potent chemical explosives manufactured, although a number of newer ones, including HNIW, TKX-50, and ONC, are more powerful.
