The synthesis of 5-bromo-2-chloro-3-nitro-4-methylpyridine can be investigated in many ways. First, a suitable pyridine derivative is used as the starting material, and bromine and chlorine atoms are introduced by halogenation reaction. If methyl-containing pyridine is selected, under specific conditions, brominating reagents, such as bromine or N-bromosuccinimide (NBS), are used to bromide methyl ortho or para-sites under the control of appropriate catalyst and reaction temperature and time to obtain bromine-containing pyridine derivatives.

This compound is easily decomposed by heat, and the temperature is too high or it may cause deterioration and safety, so the storage environment temperature should be controlled within an appropriate range. And because it is sensitive to humidity, humid environment or chemical reactions, it should be kept dry.
Second, be sure to store it separately from oxidants, reducing agents, acids, bases and other substances. This compound has a specific chemical activity, comes into contact with the above substances, or causes violent chemical reactions, such as combustion, explosion and other serious consequences.
Third, the storage container should be made of suitable materials to ensure a good seal. Corrosion-resistant glass bottles or specific plastic containers can be selected to prevent compound leakage. And on the container, there should be a clear label, indicating the name, properties and hazards of the compound and other key information.
Fourth, during transportation, it is also necessary to strictly abide by relevant regulations. Professional transportation tools need to be used, and appropriate protective measures should be taken to prevent vibration, collision and leakage. Transportation personnel should be professionally trained and familiar with the characteristics of the compound and emergency treatment methods.
Fifth, whether it is storage or transportation, a complete emergency plan should be developed. In the event of an accident such as a leak, it can be responded to quickly and effectively to reduce the harm. Such as equipping with corresponding plugging materials, protective equipment and emergency treatment drugs.
In this way, careful attention to the details of storage and transportation can ensure the safety and stability of 5-bromo-2-chloro-3-nitro-4-methylpyridine during circulation.

5-Bromo-2-chloro-3-nitro-4-methylpyridine, the price of this product in the market is difficult to determine. The change in its price is related to multiple ends.
First, the difficulty of its preparation is the main reason. If the preparation method is complicated, requires multiple steps of reaction, and the raw materials are rare and expensive, or the conditions are harsh, the cost will be high, and the market price will follow.
Second, the state of supply and demand affects its price. If there are many people who want it, but there are few products. If it is used for the research and development of special drugs and high-tech materials, the demand will surge, and the supply will be difficult, and the price will rise. On the contrary, if the market is oversupplied, the price will drop.
Furthermore, the price of raw materials also has an impact. To prepare this pyridine derivative, if the price of the raw materials used fluctuates frequently, the final price will not be stable.
In addition, different manufacturers have different processes and different costs, resulting in poor market pricing. Large factories may be able to offer it at a lower price due to the benefits of scale and excellent technology; small factories may be slightly more expensive due to high costs.
According to past transactions, its price fluctuates quite a lot. In some cases, the price per gram may be in the tens of yuan; in other cases, due to various factors, it may be more than 100 yuan, or even higher. Therefore, to know the exact price range between markets, it is advisable to consult chemical raw material suppliers and trading platforms in real time to obtain the current accurate price.
