5-Amino-2-bromo-3-methylpyridine is a kind of organic compound. It has unique physical properties, let me tell you one by one.
First of all, its properties, under normal conditions, are mostly solid, or crystalline, with a more delicate texture. The color of this substance is often in the range of white to light yellow, with pure color and few variegated colors.
On the melting point, it has been investigated by many local experiments and is about a specific temperature range. The exact value of the melting point varies slightly due to slight differences in experimental conditions, but it is roughly within a certain range. This is one of its important physical characteristics, which can be used for reference when identifying and purifying the substance.
As for solubility, it exhibits unique solubility characteristics in organic solvents. Common organic solvents, such as ethanol and acetone, have a certain solubility. This property makes it participate in many chemical reactions in the state of solution, and it is also convenient for separation and purification operations. In water, its solubility is relatively limited, which is determined by the characteristics of its molecular structure.
Then again, its density, after precise measurement, also has corresponding values. The size of the density is related to its physical behavior such as sedimentation and stratification in the mixture. It is of great guiding significance in practical applications, such as material mixing and separation in chemical production. The physical properties of 5-amino-2-bromo-3-methylpyridine, ranging from its properties, melting point, solubility, and density, lay a solid foundation not only for the understanding of this substance, but also for its application in many fields such as organic synthesis and drug development.

The synthesis of 5-amino-2-bromo-3-methylpyridine follows several paths. First, it can be obtained by starting from suitable pyridine derivatives and by a series of reactions such as halogenation and amination.
First, take a methyl-containing pyridine substrate, and use a specific halogenating agent, such as bromine, under suitable reaction conditions to brominate at a specific position in the pyridine ring. In this case, the choice of reaction temperature, solvent and catalyst is crucial. For example, at low temperatures and in the presence of suitable catalysts, bromine atoms can be selectively introduced into the desired position to obtain 2-bromo-3-methylpyridine intermediates. < Br >
Then, the intermediate is aminated. An ammonia source can be selected. Under high temperature and pressure or with the help of a specific catalyst, the bromine atom is replaced by an amino group to obtain 5-amino-2-bromo-3-methylpyridine. During operation, it is necessary to pay attention to the proportion of reactants, reaction time and other factors to ensure that the reaction is sufficient and the product purity.
Another way can be started from the construction of pyridine rings. Using multi-functional organic compounds, the target product is synthesized through reaction sequences such as cyclization and functional group conversion. For example, using nitrogen-containing, bromine-containing and methyl-containing organic small molecules as raw materials, through condensation, cyclization and other reactions, the pyridine ring structure is first constructed, and then subsequent modifications are made to achieve the correct distribution of amino groups, bromine atoms and methyl-based pyridine rings, so as to achieve the purpose of synthesizing 5-amino-2-bromo-3-methyl pyridine. This process involves the regulation of complex reaction conditions and the separation and purification of intermediates, but it can provide a unique synthesis strategy for product synthesis.

5-Amino-2-bromo-3-methylpyridine is an organic chemical substance. When storing, many matters need to be paid attention to.
The choice of the first environment. It should be stored in a cool, dry and well-ventilated place. This is because if the compound is heated, or the chemical properties are changed, and even cause decomposition and other adverse conditions. Humid gas should not be ignored, because it may react with the substance and affect the quality.
The choice of containers. Be sure to choose suitable containers. Such as glass bottles, which have good sealing performance and can effectively block the intrusion of external substances. However, it should be noted that if the substance is corrosive to glass, another material needs to be selected, such as containers made of specific plastic materials, but the selected plastic should not react with 5-amino-2-bromo-3-methylpyridine.
Furthermore, isolation is essential. Do not mix with oxidizing agents, acids, alkalis and other substances. Due to the chemical activity of this compound, contact with the above substances is likely to trigger violent chemical reactions, or heat generation, combustion and even explosion, which is extremely harmful.
In addition, clear labels are also essential. On the storage container, key information such as the name, properties, and hazard warnings of the compound should be clearly marked. In this way, when using it, the operator can quickly know the relevant precautions and avoid the risk caused by unclear knowledge.
The storage site should also be equipped with corresponding fire protection and leakage emergency treatment equipment. In case of leakage, it can be responded to in time to prevent the situation from worsening and ensure the safety of personnel and the environment from serious pollution. In this way, the storage of 5-amino-2-bromo-3-methylpyridine is guaranteed to be stable.

5-Amino-2-bromo-3-methylpyridine, the market price range of this product is difficult to determine. Its price is influenced by many factors, such as supply and demand, difficulty in production, quality, and even changes in the market.
Looking at the past market conditions, if the quality is ordinary, if the bulk purchase, the price per gram may be in the tens of yuan. However, if you want high purity, and the amount is small, the price per gram may rise to more than 100 yuan. In the big market of chemical raw materials, if the supply and demand are balanced, the price may stabilize; if you need to supply less, the price will skyrocket.
Furthermore, the preparation process is also the key. If the production method is complicated, time-consuming and costly, the cost is high, and the price is also high. Quality is related to the use. For pharmaceutical research and development, it must be of high purity and the price is high; for industrial general use, if the purity is slightly lower, the price may be close to the people.
In summary, if you want to know the exact price, you need to consult the chemical raw material supplier, and explore the price in detail according to the current market and the quality and quantity you need.
