Guanidine nitrate is the salt formed from guanidine and nitric acid. It has the chemical formula C(NH2)3NO3. It has been used as a monopropellant in the Jetex engine for model airplanes. It is attractive because it has a high gas output and low flame temperature. It has a relatively high monopropellant specific impulse of 177 seconds ().[note 1]
- May explosively decompose on shock, friction, or concussion.
- May explode on heating.
- On combustion, forms toxic and corrosive fumes including nitric acid and nitrogen oxides.
- The substance is a strong oxidant and reacts with combustible and reducing materials.
Routes of exposure:
- The substance can be absorbed into the body by ingestion.
- A nuisance-causing concentration of airborne particles can be reached quickly when dispersed, especially if powdered.
Effects of short-term exposure:
- The substance is severely irritating to the eyes and the skin.
- Harmful if inhaled, swallowed or absorbed through the skin.
