The synthesis method of 2-amino-5-bromopyridine, through the ages, many parties have their own wonderful methods. First, using 5-bromopyridine-2-carboxylic acid as the starting material, it is first converted into the corresponding acyl chloride, and then reacted with ammonia to form an amide, and finally degraded by Hoffman, 2-amino-5-bromopyridine can be obtained. During this process, the preparation of acyl chloride needs to pay attention to the reaction conditions to prevent side reactions from breeding. When Hoffman degrades, the amount of base and the reaction temperature are also key, and precise control is required to obtain the best effect.
Second, starting from 2-chloro-5-bromopyridine, ammonia is used as a nucleophilic reagent. Under suitable solvent and temperature, a nucleophilic substitution reaction occurs, so that the chlorine atom is replaced by an amino group, so as to obtain this target product. However, in this process, the polarity of the solvent and the concentration of ammonia have a great impact on the reaction rate and yield. Choosing suitable solvents, such as N, N-dimethylformamide, etc., can promote the smooth progress of the reaction.
Third, 5-bromo-2-nitropyridine is used as raw material, and the nitro group is converted into an amino group through reduction reaction, so 2-amino-5-bromo-pyridine is obtained. Commonly used reducing agents include iron powder, zinc powder, etc., which are reacted in acidic media. However, the post-reaction treatment is slightly more complicated, and careful separation and purification are required to remove impurities and obtain a pure product.
All synthesis methods have advantages and disadvantages. In actual operation, when the availability of raw materials, the difficulty of reaction, cost considerations, and the purity requirements of the product are many factors, careful choices can be made to achieve efficient, economical, and high-quality synthesis.

2-Amino-5-bromopyridine is one of the organic compounds. Its physical properties are particularly important and it is widely used in various fields of chemistry.
Looking at its properties, at room temperature, it is mostly white to light yellow crystalline powder, which is easy to identify and process. Its melting point range is about 128-132 ° C. This melting point characteristic can help to identify the purity and cover the change of melting point caused by the mixing of impurities.
2-amino-5-bromopyridine also has characteristics in terms of solubility. It is slightly soluble in water, but it has good solubility in organic solvents such as ethanol, dichloromethane, N, N-dimethylformamide (DMF), etc. In ethanol, with the increase of temperature, the solubility gradually increases. This is because the temperature increases, the thermal movement of molecules intensifies, and the interaction between solute and solvent molecules enhances. In dichloromethane, because its molecular structure is similar to dichloromethane, it can also dissolve well according to the principle of similar miscibility.
The stability of this compound is also worthy of investigation. Under normal conditions, it is quite stable, but when it encounters strong oxidizing agents, strong acids or strong bases, the structure is easily damaged. In case of strong acid, the amino group is easily protonated, causing its chemical properties to change; in case of strong alkali, it may initiate reactions on the pyridine ring. And light and high temperature environment may also promote decomposition or other chemical reactions, so when storing, it should be placed in a cool, dry and dark place to prevent deterioration.
The physical properties of 2-amino-5-bromopyridine, such as appearance, melting point, solubility and stability, are key considerations in many fields such as organic synthesis and pharmaceutical chemistry, and play a decisive role in its reactivity and application.

In today's world, business conditions change, and it is difficult to determine the price of 2-amino-5-bromopyridine on the market. The price is affected by various factors, and it cannot be said in a word.
The abundance of raw materials is the main reason. If the raw materials required for the production of this compound are in good weather in the production area and the output is full, the cost may drop, and the price in the market may also decrease. On the contrary, if the origin of raw materials encounters a disaster and the supply is in short supply, the price will rise.
The quality of the process is also important. Advanced and exquisite production technology can make the output efficient and high-quality, so that the price may be stable, or even slightly reduced due to proper cost control. However, if the process is outdated, inefficient, and defects are frequent, the price may not be close to the people.
The supply and demand of the market is particularly affected. If the demand for 2-amino-5-bromopyridine surges in many industries for a while, and the supply is difficult to respond in time, the price will soar. If the demand is light and the supply is surplus, the price will fall.
It is also in line with the current situation, and the policy regulations can make the price fluctuate. The increase and decrease of tariffs between international trade and the blockage of transportation also affect the price.
Therefore, in order to know the exact market price of 2-amino-5-bromopyridine at present, it is necessary to visit various suppliers, observe the market dynamics in detail, and review the information of all parties to obtain a relatively accurate price. And this price may change with the circulation of the sun and the moon, and it is necessary to pay attention to it from time to time to understand it.

2-Amino-5-bromopyridine is one of the organic compounds. Its storage conditions are crucial and related to the stability and quality of this compound.
To properly store this compound, the first environment is dry. Moisture can easily cause it to deteriorate, because 2-amino-5-bromopyridine encounters water or humid air, or reacts chemically, damaging its chemical structure and properties. Therefore, it should be stored in a dry place, such as a sealed container equipped with a desiccant, which can effectively block moisture.
Temperature is also a key factor. Generally speaking, it should be stored in a cool place to avoid high temperatures. High temperature can accelerate its decomposition or cause other adverse reactions. The ideal storage temperature is between - 20 ° C and 25 ° C. Low temperature can slow down the chemical reaction rate, but too low temperature may cause crystallization or solidification, which is inconvenient to use.
Light cannot be ignored. 2-Amino-5-bromopyridine is sensitive to light, and long-term light exposure may cause it to degrade. Therefore, when storing, it is advisable to use a brown bottle or a container wrapped in dark materials to prevent light exposure.
In addition, the storage place should be kept away from fire sources, oxidants and strong acids and bases. Because of its certain chemical activity, contact with these substances may cause violent reactions and cause safety accidents. < Br >
Proper storage of 2-amino-5-bromopyridine requires a dry, cool, dark environment and avoidance of contact with incompatible substances to ensure its quality and stability for subsequent experiments or production.
