Nitroguanidine (CH4N4O2)

Nitroguanidine- abbreviated NGu or NQ- is a colorless, crystalline solid that melts at 257 °C and decomposes at 254 °C. NGu is an extremely insensitive but powerful high explosive. Wetting NGu with > 20 wt.-% water effects desensitization from HD 1.1 down to HD 4.1 (flammable solid). NGu is used as an energetic material (propellants, High explosives), precursor for insecticides, and for other purposes. Nitroguanidine is in use since the 1930s as an ingredient in triple-base gun propellants in which it reduces flame temperature, muzzle flash and erosion of the gun barrel but preserves chamber pressure due to high nitrogen content. Its extreme insensitivity combined with low cost has made NGu ...View all
