The synthesis of 3-bromo-5-chloro-2-cyanopyridine has been known for a long time. First, pyridine is used as the starting material, and bromine and chlorine atoms are introduced into the pyridine ring by halogenation. This halogenation method requires the selection of a suitable halogenating agent, such as liquid bromine for the brominating agent, supplemented by a catalyst such as iron powder, etc., to promote the reaction to obtain bromine-containing pyridine derivatives. Then a chlorination agent, such as chlorine gas or chlorination reagent, is used to react under specific conditions to connect the chlorine atom to the pyridine ring to obtain 3-bromo-5-chloropyridine.
Then, to introduce the cyanyl group, the method of nucleophilic substitution can be used. The 3-bromo-5-chloropyridine and the cyanide reagent, such as cuprous cyanide, are reacted in a suitable solvent at a certain temperature and pressure. The solvent is often selected as a polar organic solvent, such as dimethylformamide (DMF), to facilitate the sufficient reaction. The cyanyl group replaces the bromine atom or the chlorine atom to obtain 3-bromo-5-chloro-2-cyanopyridine.
Another synthesis method can be started from the pyridine derivative containing the cyanide group. The cyanopyridine-containing structure is first constructed by a suitable method, and then the halogenation reaction is carried out. At the time of halogenation, the reaction conditions, including temperature, time, and the proportion of reactants, are precisely controlled, so that the bromine and chlorine atoms are connected to the pyridine ring at the desired position, and the target product can also be obtained. Although these methods are different, they all need to fine-tune the reaction conditions to achieve the effect of synthesis and obtain pure 3-bromo-5-chloro-2-cyanopyridine.

3-Bromo-5-chloro-2-cyanopyridine, this is an organic compound. Looking at its physical properties, at room temperature, it is mostly in a solid state, but the exact number of its melting point and boiling point is difficult to tell precisely because the relevant records are not detailed. This substance exhibits a certain solubility in organic solvents, such as common ethanol, ether, dichloromethane, etc. However, in water, the solubility is quite low. This is because the compound contains cyanide groups, halogen atoms, etc., and has a certain polarity, but is not extremely strong. Therefore, it is soluble in polar organic solvents and insoluble in water.
When it comes to stability, the compound is relatively stable. The presence of cyanide groups makes its chemical properties unique. The carbon-nitrogen triple bond in the cyanyl group has high chemical activity and can participate in a variety of chemical reactions. Bromine and chlorine atoms are also important activity check points and can play a key role in reactions such as nucleophilic substitution. For example, when suitable nucleophilic reagents exist, bromine and chlorine atoms can be replaced by nucleophilic reagents, and many new compounds can be derived.
In addition, in the 3-bromo-5-chloro-2-cyanopyridine molecule, the pyridine ring gives it a certain alkalinity, but compared with common organic bases, its alkalinity is weaker. The nitrogen atom on the pyridine ring has lone pairs of electrons, which can accept protons, but the electronic effect of the substituents on the ring affects its alkalinity. This compound is widely used in the field of organic synthesis and can be used as a key intermediate to prepare special compounds in the fields of medicine, pesticides, materials, etc.

3-Bromo-5-chloro-2-cyanopyridine, the price of this product in the market is difficult to determine. The change in its price is related to many reasons.
First, the method of production and cost are the most important. If the preparation method is exquisite, the raw materials are easy to obtain and cheap, and the labor cost is saved, the price may become more affordable. On the contrary, if the production method is complicated, the raw materials are rare and expensive, and the manpower and material resources required are huge, the price will be high.
Second, the trend of supply and demand determines the price. If there are many in the market, it is used in medicine, agrochemical and other industries, and the supply is small, the price will rise. If there are many producers, but there is little demand, and the goods are stocked in the market, the price may drop.
Furthermore, the competition in the market also has an impact. Businesses compete to sell, to compete for customers to profit, or to reduce prices. And if the market is monopolized and exclusively supplied, the price can be controlled by their hands, and the level can be determined.
Re-existence, changes in the current situation, tariffs, transportation costs, etc., can all lead to price movements. The current situation is unstable, raw materials are difficult to harvest, or tariffs are increased, and transportation costs are increased, all of which increase costs and prices.
From this perspective, if you want to know the exact price of 3-bromo-5-chloro-2-cyanopyridine, you must carefully investigate all these reasons, and you need to consult the merchants in the industry, the brokers in the market, or refer to the transaction history and market conditions reports to obtain a more accurate number. However, the market conditions are ever-changing, and the price is also variable, so the price is ultimately difficult to explain.

3-Bromo-5-chloro-2-cyanopyridine is an important raw material in organic synthesis. During storage and transportation, many key matters need to be paid attention to.
When storing, the first environmental conditions should be. It should be placed in a cool, dry and well-ventilated place. This compound is quite sensitive to humidity, and humid environments can easily cause it to deteriorate, so it is necessary to ensure that the storage environment is dry. And the temperature should also be suitable. If the temperature is too high or chemical reactions are triggered, its stability will be damaged.
Secondly, the choice of storage container is also crucial. Choose a container with good sealing performance to prevent contact with air. Due to the reaction of oxygen, water vapor and other components in the air or with the compound. Generally speaking, glass containers or specific plastic containers are more suitable, but it is necessary to ensure that the material of the container does not chemically react with 3-bromo-5-chloro-2-cyanopyridine.
Furthermore, it should be stored separately from oxidants, acids, bases and other substances. Due to its active chemical properties, contact with these substances or cause violent reactions, which may even lead to dangerous accidents.
As for transportation, the relevant transportation regulations must be strictly followed. Transportation vehicles need to have good ventilation conditions to reduce the risk caused by the accumulation of volatile gases. And severe vibration and collision should be avoided during transportation to prevent package damage.
Packaging must be strong and well sealed. Packaging materials must be able to effectively resist the influence of external factors on 3-bromo-5-chloro-2-cyanopyridine. Once the package is damaged, immediate measures should be taken to prevent the spread of leaks, and timely cleaning and proper handling.
Transportation personnel also need to undergo professional training, familiar with the characteristics of the compound and emergency treatment methods. In the event of an accident during transportation, such as a leak, they can take prompt and correct response measures to ensure the safety of personnel and the environment.
