Nitroguanidin is an energetic, very stable chemical compound, which attained great importance as component of propellant powders and safety explosives.

Nitroguanidin is a very sturdy explosive, which is characterised by particularly low detonation energy, at a detonation speed, which is nearly as high as from RDX.

Production and representation

Nitroguanidin develops for CH6N4O3 during the effect of cold concentrated sulfuric acid on Guanidiniumnitrat [506-93-4].


Nitroguanidin is moderately explosively and detonated only with a

Nitroguanidin trains colorless, orthorhombische, needle-shaped crystals. Its density amounts to 1.78 g/cm its melting point lies with 239"°C (Subl., Zers.). Nitroguanidin is not hygroscopic. It is with difficulty solubly in cold water, methanol and ethanol, soluble in hot water (slow hydrolysis), acids and Basen (decomposition). It forms addition compounds with Ketonen and alcohols.

Nitroguanidin exists in two forms: (stable) and Both forms are not changed by recrystallization from water, glacial acetic acid or ammonia.

If in 96%-iger sulfuric acid is solved and if the solution is registered in water, then a-Nitroguanidin separates.


Nitroguanidin becomes as component of gas generator corroding (so-called Airbagpropellants) and of so-called "cold" propellant powders uses, which preserve the runs and fewer muzzle flashes give. It is more insensitively to impact, friction and impact than TNT, however in explosiveness (chemistry), achievement and blowing up characteristic comparable to this.

Nitroguanidin comes as fine-noble LBDNQ (low bulk density nitroguanidine) as well as granular HBDNQ (high bulk density NQ) and very rarely as spherical SHBDNQ (spherical high bulk density NQ) into the trade.
