However, if the ambient temperature is too high, the chemical bond vibration in the molecule will intensify, which may cause structural changes and reduce stability; when the humidity is too high, water molecules may participate in the process of changing their molecular structure and affect their chemical properties. In addition, light, especially ultraviolet radiation, may trigger photochemical reactions and destroy its molecular structure, so it needs to be properly stored under low temperature, dry and dark conditions to maintain the stability of its structure and properties.
- ** Melting point **: Has a specific melting point, when the temperature rises to a certain exact value, the substance will change from solid to liquid. This melting point value is crucial for identifying this substance and controlling its application in high temperature environments. By measuring the melting point, it can assist in judging the purity and structural integrity of the substance.

The synthesis method of 5-aminoimidazole-2-formamide has been known for a long time, and is now described in Chinese.
First, the corresponding halogenate is used as the starting material. Take halogenated imidazole derivatives and reagents containing aminoformyl groups in suitable solvents, such as alcohols, ethers or aromatic hydrocarbon solvents, and use bases as catalysts, such as potassium carbonate, sodium carbonate or organic bases, etc., to control the temperature and slowly react. During this process, halogen atoms and aminoformyl groups undergo a substitution reaction to form 5-aminoimidazole-2-formamide. The principle lies in the activity of halogen atoms, which is easily replaced by nucleophiles, and the existence of bases can promote the progress of the reaction, adjust the pH of the reaction system, and move the reaction in the direction of generating the target product.
Second, it is formed by cyclization reaction. Select compounds containing nitrogen and carbonyl groups, and under specific conditions, make them cyclize in the molecule. For example, with suitable amides and nitriles, under the catalysis of strong acids or strong bases, in a high temperature environment, the groups in the molecule are rearranged and cyclized to construct an imidazole ring structure, and then 5-aminimidazole-2-formamide is formed. This method focuses on the rearrangement and cyclization of intramolecular chemical bonds, and cleverly uses the structural characteristics of the compound itself to achieve the synthesis of the target product through the regulation of external conditions. The control of reaction conditions is extremely critical. The type and concentration of strong acid or strong base, and the specific degree of high temperature will affect the rate of reaction and the purity of the product.
Third, biosynthesis is also involved. Using the catalytic properties of microorganisms or enzymes to synthesize by specific metabolic pathways. During the growth and metabolism process of some microorganisms, simple carbon sources, nitrogen sources and other substances can be gradually synthesized 5-aminoimidazole-2-formamide through complex enzymatic reactions in the body. This method has the advantages of green, high efficiency, and strong selectivity, but it requires strict environmental requirements for the reaction, requires precise control of microbial growth conditions, such as temperature, pH, nutrient concentration, etc., and the screening and cultivation of microorganisms also requires a lot of effort.
