Description of key information
Additional information
Appearance
Nitroguanidine is a colourless and odourless crystalline powder.
Melting point
The melting point of nitroguanidine cannot be determined because the test material decomposes before the melting point is reached. The decomposition temperature is at about 232 °C.
Boiling point
The boiling point of nitroguanidine cannot be determined because the test material decomposes before the boiling point is reached.
Density
The density of nitroguanidine is ρ20 = 1.760 g/cm³
Particle size distribution
The median value of particle size of nitroguanidine is 9.88 µm.
Vapour pressure
The vapour pressure of nitroguanidine is estimated to be 0.000000000646 Pa
Partition coefficient
The octanol/water partition coefficient for nitroguanidine is low: log Kow = -0.815
Water solubility
The solubility of Nitroguanidine in water is 3.0 g/L at 20 °C
Surface tension
Nitroguanidine is considered not surface active.
Flash Point
The vapour pressure of Nitroguanidine is to low the yield a flash point.
Flammability
Nitroguanidine is not highly flammable.
Explosiveness
Nitroguanidine is sensitive to detonator and therefore classified as explosive.
Oxidising properties
Oxidising properties aren't determined because of the explosive properties
Stability in organic solvents
The substance is not handled or sold in organic solvents. In accordance with REACH annex IX the stability in organic substances is not considered to be critical.
Dissociation constant
The dissociation constant (KD) of nitroguanidine was determined to be pKD = 1.43.
Viscosity
Viscosity of Nitroguanidine was not determined because it is a solid.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
