2-Amino-5-nitrobenzimidazole is one of the organic compounds. It has specific physical and chemical properties, which are described in detail by you today.
First of all, its physical properties. This substance is mostly solid under normal conditions, colored or white-like powder, with a delicate appearance. Its melting point is quite high, and it requires more energy to melt it because of its strong intermolecular force. As for solubility, it is limited in common organic solvents such as ethanol and acetone, but it can have a certain solubility in strong polar solvents such as dimethyl sulfoxide (DMSO). This is because of the similar miscibility, its molecular structure contains polar groups, and it is easier to interact with strong polar solvents.
Describe its chemical properties. Because of its structure containing amino and nitro groups, it has unique chemical activity. Amino is the power supply group, which can increase the electron cloud density of the benzimidazole ring, making it prone to electrophilic substitution reactions, such as halogenation, nitrification, etc. Nitro is a strong electron-absorbing group, which reduces the electron cloud density of the benzimidazole ring, and can participate in various reactions, such as nitro reduction reaction, which can be converted into amino groups under suitable conditions, resulting in the derivation of more compounds. And because it is in the benzimidazole system, it has both the chemical stability and reactivity of the system, and can participate in many organic reactions such as cyclization and condensation. It has a wide range of uses in the field of organic synthesis.
In summary, 2-amino-5-nitrobenzimidazole has important applications and research values in many fields such as medicinal chemistry and materials science due to its special physicochemical properties.

The synthesis of 2-amino-5-nitrobenzimidazole is a key research field in organic synthetic chemistry. In the past, many scholars have studied this, and now let's give a general overview.
First of all, o-phenylenediamine is used as the starting material, which is the foundation of synthesis. Co-heating of o-phenylenediamine and formic acid, the two then start a condensation reaction. At a suitable temperature, duration and reactant ratio, the condensation reaction proceeds in an orderly manner to produce benzimidazole. In this process, temperature control is of paramount importance. If the temperature is too high, or side reactions may occur, and the product is impure; if the temperature is too low, the reaction rate is slow and takes a long time. The benzimidazole produced by
is then nitrified to introduce nitro groups. Mixed acids (mixed solutions of nitric acid and sulfuric acid) are often used as nitrifying reagents. The concentration of mixed acids, reaction temperature and time are all factors that affect the nitrification reaction. Only by precisely regulating these conditions can nitro groups be selectively introduced into the 5-position of benzimidazole to obtain 5-nitrobenzimidazole. If the conditions are improper, the nitro group may be introduced into other positions, resulting in complicated products and difficult separation and purification.
After 5-nitrobenzimidazole is obtained, the nitro group is reduced to an amino group by suitable reduction methods, and then 2-amino-5-nitrobenzimidazole is formed. The reduction method can be selected as catalytic hydrogenation, using precious metals (such as palladium carbon) as catalysts to react in a hydrogen atmosphere. Chemical reduction can also be used, such as iron powder, zinc powder and other metals and acids for reduction. Although the catalytic hydrogenation method has the advantages of high efficiency and cleanliness, it requires strict equipment and requires pressure-resistant and hydrogen-resistant devices; the chemical reduction method is relatively simple, but there may be many by-products, and the generated waste needs to be properly disposed of.
The whole process of synthesis, the fine control of the reaction conditions, and the purity detection, separation and purification of the intermediate product and the final product are all the keys to obtaining high-purity 2-amino-5-nitrobenzimidazole. Each step is closely interconnected, and any mistake in any step can affect the quality and yield of the final product.

In today's world, business conditions are unpredictable, and it is difficult to determine the price of 2-amino-5-nitro-benzimidazole on the market. The price of this product is often influenced by many factors, such as the situation of supply and demand, the amount of raw materials, the simplicity of craftsmanship, market competition, and even changes in the current situation and regulations of the government.
The market situation in the past may be able to be measured. However, at that time, prices also fluctuated with the passage of time. Looking at the past, its price may have risen due to a temporary increase in demand; or it may have fallen due to the abundance of raw materials and the increase in production capacity.
And different regions and different merchants have different prices due to their different costs and different business practices. Therefore, in order to know the exact price range of this item, it is necessary to carefully investigate the current market and visit all merchants to get a closer estimate. However, in general, due to the above many variables, its price range is difficult to be covered in one word, and it is necessary to study the current facts carefully before we can be sure.

2-Amino-5-nitro-benzimidazole is an organic compound, and its storage conditions are very critical, which is related to the stability and quality of this compound. According to the principles of "Tiangong Kaiwu", the storage needs to be checked for its properties and appropriate.
2-Amino-5-nitro-benzimidazole has certain chemical activity and is easily affected by external factors. First, it should be stored in a cool place. Extreme heat can easily promote its chemical reaction, causing decomposition or deterioration. In summer, exposure to hot sun makes it vulnerable. The same is true for this compound. Shade can slow down the speed of its chemical change.
Second, a dry environment is indispensable. Moisture can easily make the compound absorb moisture, or cause reactions such as hydrolysis. If it is in a humid place, such as the rainy season in the south of the Yangtze River, it is easy to get damp, so it is necessary to choose a drying place, such as placing the desiccant in the storage place to keep it dry.
Third, avoid contact with oxidants. 2-Amino-5-nitro-benzimidazole structure contains amino and nitro groups, which can react violently in case of oxidants, and even cause explosions and other dangers. Therefore, it needs to be separated from the oxidant to ensure safety.
Fourth, storage containers are also exquisite. Corrosion-resistant containers, such as glass or specific plastic materials, should be used. Due to its chemical activity, ordinary metal containers or reactions with them affect the purity and quality of compounds.
In short, 2-amino-5-nitro-benzimidazole should be stored in a cool, dry, protected from oxidants, and selected in a suitable container, so as to ensure its quality and stability for subsequent use.
