2-Amino-6-nitropyridine (97%), its physicochemical properties are quite important. This substance is in the state of light yellow to brown crystalline powder, and it has its unique appearance. Its melting point is between 188-192 ° C, which is of key significance in identification and application.
In terms of solubility, it is slightly soluble in water, but it has a certain solubility in organic solvents such as ethanol and dichloromethane. This difference in solubility requires attention when operating in different media.
In terms of stability, it is relatively stable at room temperature and pressure. However, it is necessary to avoid contact with strong oxidants, strong acids, strong bases, etc., to prevent violent reactions. Because it contains amino and nitro groups, its chemical activity cannot be underestimated. Amino groups are alkaline to a certain extent, while nitro groups change the electron cloud density of the pyridine ring, affecting the overall chemical properties.
2-Amino-6-nitropyridine is widely used in the field of organic synthesis. It can be used as a key intermediate and participates in the preparation of many drugs, pesticides and functional materials. Knowing its physical and chemical properties is a prerequisite for rational and safe use. It is of indispensable value in chemical production, scientific research and exploration.

2-Amino-6-nitropyridine (97%) requires attention to many matters when storing. This is a fine chemical with special properties, and the storage method is related to its quality and safety.
First, it should be placed in a cool and well-ventilated place. Extreme heat or poor ventilation can easily cause the temperature to rise, or cause the product to undergo a chemical reaction, which affects the purity and performance. Just like ancient people's collections, choose a cool and dry place to keep the item intact for a long time.
Second, keep away from fire and heat sources. This product may be flammable. In case of an open flame or hot topic, it may cause a fire or even an explosion, endangering life and property safety. Just like the ancients who were fireproof and kept away from fire sources to ensure safety.
Third, it should be stored separately from oxidizers, acids, etc. Because the product comes into contact with these substances, or reacts violently, resulting in accidents. Just like the ancients kept things, things with different attributes should be placed separately to avoid mutual interference.
Fourth, the storage place should be equipped with suitable containment materials. In case of leakage, it can be collected and processed in time to avoid polluting the environment and causing greater harm. Just like rain gear needs to be prepared to prevent being drenched.
Fifth, the storage container must be well sealed. If the seal is not good, it is easy to react with the ingredients in the air, or cause volatilization, reducing the content, just like the ancient wine, tightly sealed to preserve the aroma.
In short, store 2-amino-6-nitropyridine (97%), when following the above points carefully to ensure safety and quality.

The preparation method of 2-amino-6-nitropyridine (97%), although the ancient book "Tiangong Kaiwu" does not describe this specific compound in detail, it can be reasonably deduced according to the chemical process of the past.
In the past, nitrogen-containing heterocyclic compounds were often prepared with pyridine as the starting material. To obtain 2-amino-6-nitropyridine, pyridine can be nitrified first. The pyridine ring has a certain electron cloud distribution characteristics, and under suitable conditions, nitro can be selectively introduced into the 6-position. If the mixed acid of concentrated nitric acid and concentrated sulfuric acid is used as the nitrifying agent, the pyridine can be nitrified to obtain 6-nitropyridine under temperature control and control. This step requires attention to the reaction conditions to prevent excessive nitrification or formation of by-products.
After 6-nitropyridine is obtained, amination is performed. The method of amination may be aminolysis. React with 6-nitropyridine with appropriate amination reagents, such as liquid ammonia, in the presence of a catalyst. The catalyst can help reduce the activation energy of the reaction and improve the reaction rate and selectivity. During the reaction, attention should be paid to controlling the reaction temperature, pressure and material ratio, so that the amino group can be successfully introduced into the 2-position, and finally 2-amino-6-nitropyridine is obtained. In the preparation process of
, it is necessary to carefully control the reaction conditions of each step, and purify and identify the product at each step to ensure the purity of the product and the reaction yield, in order to achieve the purity requirement of 97%. Although the ancient process is different from today, this reasoning method may reflect the idea of preparing the compound.

The market price of 2-Amino-6-nitropyridine (2-amino-6-nitropyridine, 97% content) varies with time, place and supply and demand. Looking at past market conditions, its price fluctuations are quite complicated.
In the past, when the market for chemical raw materials was stable, the price of such high-purity chemical reagents may be in the range of hundreds of yuan per kilogram. If the purchase volume is large, the supplier may reduce the unit price slightly due to economies of scale, and there may be discounts of tens of yuan per kilogram.
When the market changes, in case of scarcity of raw materials, changes in production processes or policy controls, the price also fluctuates sharply. For example, at some point, due to the limited supply of key raw materials, the price of 2-Amino-6-nitropyridine rises sharply, or more than 1,000 yuan per kilogram. Or due to the advent of new technologies, production efficiency has increased greatly, supply exceeds demand, and prices may drop below hundreds of yuan per kilogram.
Furthermore, prices vary in different regions. Economically developed and chemical industry concentrated places, due to convenient logistics and fierce competition, prices may be relatively close to the people; while remote and inconvenient transportation, due to the superposition of transportation costs, prices are often higher.
Therefore, in order to know the current exact market price of 2-Amino-6-nitropyridine (97%), when consulting chemical product suppliers, browsing professional chemical trading platforms or referring to recent market survey reports, the accurate number can be obtained.
