Nitroguanidine - sometimes abbreviated NQ or NGu - is a colorless, crystalline solid that decomposes at 239 °C (462 °F), without melting. Nitroguanidine is an extremely insensitive but powerful high explosive. Nitroguanidine is used as an energetic material (propellant or high explosive), precursor for insecticides, and for other purposes.
