Guanidine Nitrate can be made by melting a mixture of ammonium nitrate, urea with silica gel.
All reagents must be dry and well mixed. When the temperature reaches 160 °C, the molten mixture begins to foam and releases ammonia.
To prevent the reagents from spilling all over your table, you will have to strongly stir the mixture for at least a couple of hours.
The use of silica gel is absolutely necessary, as molten ammonium nitrate mixed with another organic material may explode if the mixture is too pure or the temperature is too high.
Two reactions occur during the process: NH4NO3 + (NH2)2CO → C(NH2)3NO3 + NH4COONH2
NH4COONH2 → 2 NH3 + CO2
A different method replaces urea with calcium cyanamide.
While it can be made by reacting stoichiometric amounts of guanidine with nitric acid, freebase guanidine is difficult to find. Guanidinium carbonate or bicarbonate can be used instead as they're cheaper and more available.
In nature and industry, Guanidine Nitrate is not commonly found naturally; it is typically produced synthetically by neutralizing guanidine with nitric acid.
The compound is chemically stable under normal storage conditions, but due to its oxidizing nature, it can participate in exothermic reactions if it comes into contact with flammable, reducing, or combustible materials.
Guanidine Nitrate is therefore handled with care in laboratories and industrial facilities, stored in cool, dry, well-ventilated areas, and kept away from heat, sparks, and incompatible chemicals.
Guanidine Nitrate is a versatile nitrogen-rich inorganic salt with properties that make it valuable in energetic, chemical, and industrial applications, but it requires careful handling due to its oxidizing nature and potential reactivity under certain conditions.

In laboratory research, Guanidine Nitrate is used in studies of energetic materials, decomposition kinetics, and gas-generating reactions, where its predictable behavior as an oxidizing salt makes it valuable for controlled experiments.
Guanidine Nitrate is also sometimes employed as a model compound in the study of nitrogen-rich salts and their combustion properties, which contributes to the development of safer and more efficient propellants or pyrotechnic formulations.
Guanidine Nitrate is primarily valued for its energetic and oxidizing properties, which make it a critical component in solid rocket propellants, gas generators, and pyrotechnic mixtures, while its chemical reactivity also allows for specialty industrial, laboratory, and research applications that exploit its nitrogen-rich composition.

Safety Profile:
Guanidine Nitrate is a hazardous substance, being an explosive and containing an oxidant (nitrate).
Guanidine Nitrate is also harmful to the eyes, skin, and respiratory tract.
Guanidine Nitrate is considered irritating to the skin, eyes, and respiratory system, and direct contact with the skin can cause redness, itching, or dermatitis, particularly in sensitive individuals or with prolonged exposure.
Eye contact may result in burning, redness, or temporary irritation, and accidental splashes should be rinsed immediately with plenty of water.
Inhalation of dust or fine particles can cause respiratory discomfort, coughing, or throat irritation, and while it is not highly toxic, ingestion can lead to gastrointestinal upset, nausea, or vomiting, and should be avoided entirely.
Because of its oxidizing properties, it can also exacerbate skin or respiratory irritation if combined with other reactive substances, so handling in well-ventilated areas with appropriate protective equipment is essential.
Guanidine Nitrate is classified as a strong oxidizer, which means it can intensify the combustion of flammable or combustible materials and may contribute to fires or explosions if it comes into contact with organic fuels, reducing agents, or metals.
Guanidine Nitrate is particularly hazardous under conditions of heat, friction, or confinement, where decomposition can produce rapid release of gases and energy, leading to potentially violent reactions.
Therefore, it should never be stored near acids, alkalis, fuels, or strong reducing agents, and sources of heat, sparks, and open flames should be strictly avoided in areas where the chemical is present.
