The synthesis method of 3-amino-2-bromo-6-methylpyridine, although the ancient book "Tiangong Kaiwu" does not directly record the synthesis of this compound, it can be explored according to the wisdom of the ancients and modern chemical knowledge.
First, 2-bromo-6-methylpyridine is used as the starting material, and 2-bromo-3-nitro-6-methylpyridine is obtained by nitrification. In this step, in a suitable reaction vessel, add sulfuric acid and nitric acid mixed with acid, and control the temperature to make the raw material react with it. Such as the ancient alchemy and pharmaceutical, it is necessary to accurately grasp the temperature and dosage. After that, iron powder or zinc powder and hydrochloric acid are used to form a reduction system, and the nitro group is reduced to an amino group to obtain the target product 3-amino-2-bromo-6-methylpyridine. This process is similar to ancient metallurgy, using a reducing agent to convert high-valent nitro groups into amino groups.
Second, starting from 2-methyl-6-hydroxypyridine, brominate first, bromine with liquid bromine or N-bromosuccinimide (NBS) in a suitable solvent, under the action of light or initiator, brominate the hydroxyl ortho-position to obtain 2-bromo-6-methylpyridine, and then obtain the target product according to the above nitrification and reduction steps. This route is like a delicate pavilion, and the molecular structure is constructed in a step-by-step and orderly manner.
Third, using 2-methylpyridine as raw material, bromine atoms and methyl groups are first introduced under suitable conditions, and then amino groups are introduced through amination reaction. In this process, 3-amino-2-bromo-6-methylpyridine is obtained through a complex reaction process of amination reaction or ammonia and a suitable catalyst. This method is such as carefully carving jade and gradually shaping the required molecules. All methods need to pay attention to the reaction conditions, raw material purity and separation and purification to obtain high-purity products.

3-Amino-2-bromo-6-methylpyridine is one of the organic compounds. Its physical properties are quite important, let me tell them one by one.
Looking at its appearance, under normal conditions, it is mostly in a solid state. As for the color, it is often white to light yellow in powder or crystalline form. This color state is easy to identify with the naked eye. In laboratory and industrial applications, it is an important basis for preliminary discrimination.
The melting point is within a certain range. This property plays a significant role in the identification of purity and separation and purification of substances. By measuring the melting point, the purity can be judged. If the purity is high, the melting point is more sensitive and concentrated; if it contains impurities, the melting point is often reduced and the melting range becomes wider.
Solubility is also a key physical property. This compound has different solubility in common organic solvents. In some polar organic solvents, such as ethanol and dichloromethane, it has a certain solubility. This property makes it possible to choose a suitable solvent for organic synthesis reactions to facilitate the separation of the reaction and the product. In water, its solubility is relatively small. Although the molecular structure contains amino groups, it has a certain polarity, but the overall hydrophobicity is still strong, so it is difficult to dissolve in water.
Furthermore, its density also has a specific value. The determination of density is of great significance in chemical production and experimental operation, which is related to the measurement and mixing ratio of materials, and affects the reaction process and product quality.
The physical properties of 3-amino-2-bromo-6-methyl pyridine, such as appearance, melting point, solubility, density, etc., are all important characteristics of it, and are indispensable factors in many fields such as organic synthesis, drug development, and materials science. It helps researchers to understand its characteristics and make good use of it to achieve the desired purpose.

3-Amino-2-bromo-6-methylpyridine is an organic compound with unique chemical properties. Its molecules contain amino groups (-NH 2), bromine atoms (-Br) and methyl groups (-CH), which are distributed at specific positions in the pyridine ring.
In terms of alkalinity, the amino group can accept protons and is somewhat basic. However, due to the aromatic and conjugated system of the pyridine ring, the electron cloud is dispersed, and its alkalinity is weaker than that of aliphatic amines.
In terms of reactivity, bromine atoms are active and nucleophilic substitution reactions can occur. Nucleophilic test agents can attack carbon atoms connected to bromine, and bromine ions leave to form new compounds. For example, when reacted with sodium alcohol, corresponding ether derivatives can be formed.
Amino groups also participate in many reactions, such as reaction with acid chloride or acid anhydride, acylation occurs, and amide compounds are formed. This reaction is often used to introduce acyl functional groups to change molecular properties and functions.
Although methyl groups are relatively stable, under certain conditions, such as the action of strong oxidants, they can be oxidized and converted into other functional groups such as carboxyl groups.
3-amino-2-bromo-6-methylpyridine is widely used in drug synthesis, materials science and other fields due to these properties. In drug synthesis, it can be used as a key intermediate to construct molecular structures with specific biological activities. In materials science, the ability to introduce a polymer or material surface through a chemical reaction, imparting new properties to the material.

Today, there is 3-amino-2-bromo-6-methylpyridine, which is difficult to determine in the market price range. Its price often varies due to many factors, such as the difficulty of material source, the complexity of preparation process, and the amount of market demand, which are all factors that affect its price.
Looking at the market of chemical raw materials in the past, those with abundant material sources and easy preparation often have lower prices; if the sources are scarce and the preparation requires complex processes, the price will be high. And when the market demand is strong, even if the preparation is slightly easier, the price may rise; if the demand is low, even if it is not easy to get, the price will be difficult to maintain.
3-Amino-2-bromo-6-methylpyridine, if its raw materials are easily available, the preparation process is not complicated, and the market demand is not too strong, its price may be between tens of yuan and more than 100 yuan per kilogram. However, if the raw materials are scarce, the preparation requires exquisite skills and cumbersome steps, and the market is seeking it, the price may reach hundreds of yuan per kilogram, or even higher.
In summary, the price range in the market is about tens of yuan to hundreds of yuan per kilogram. It is difficult to determine a specific price, depending on the actual situation at that time.
