The synthesis method of 2-bromo-3- (bromomethyl) pyridine has been described in many books in the past. There are many methods, and the main one is selected today.
One of them can be started from 3-methylpyridine. First, under suitable reaction conditions, the methyl of 3-methylpyridine is brominated, and a bromine atom is introduced to give 3- (bromomethyl) pyridine. However, at this time, the second position of the pyridine ring does not have a bromine atom, so another method needs to be found. A suitable brominating reagent can be used to bromide the second position of the pyridine ring in a specific reaction environment to obtain 2-bromo-3- (bromomethyl) pyridine. This process requires detailed observation of the reaction temperature, time and reagent dosage. A slight difference may affect the yield and purity of the product.
Second, it can also be started from other compounds containing pyridine structures. For example, a specific pyridine derivative is selected, and the structure of the target molecule is gradually constructed after several steps of reaction. First, a specific position on the pyridine ring is functionalized, and a suitable substituent is introduced, which lays the foundation for the subsequent introduction of bromine atoms and bromomethyl. Then, the bromination and bromomethylation reactions are carried out in sequence to obtain 2-bromo-3- (bromomethyl) pyridine. This path requires careful design of each step of the reaction to ensure the smooth progress of the reaction, and the separation and purification of the intermediate products is also crucial.
Furthermore, metal-catalyzed reactions may be attempted. Using the unique activity and selectivity of metal catalysts, the reaction is guided in the direction of generating 2-bromo-3- (bromomethyl) pyridine. For example, using a specific metal salt as a catalyst and a suitable ligand, under certain solvent systems and reaction conditions, pyridine-containing substrates react with brominating reagents and bromomethylating reagents. This method requires extremely high control over the reaction conditions, and the choice and amount of catalyst also have a significant impact on the reaction results.

2-Bromo-3- (bromomethyl) pyridine is also an organic compound. It has unique physical properties, let me talk about them one by one.
Looking at its morphology, under normal temperature and pressure, it is mostly in the shape of a solid state, which is caused by intermolecular forces. Its melting point and boiling point are also important physical properties. The melting point is related to the temperature at which a substance changes from a solid state to a liquid state. The melting point of 2-bromo-3- (bromomethyl) pyridine is determined by the interaction of atoms in the molecular structure. The chemical bonds within the molecule, the spatial arrangement of bromine atoms and methyl groups, all affect the attractive forces between molecules, which in turn affect the melting point. The boiling point of
is the temperature at which a substance changes from liquid to gaseous state. In this compound, the boiling point is increased due to the large electronegativity of bromine atoms or the existence of a certain degree of weak interactions, such as dipole-dipole interactions. Therefore, its boiling point value reflects the amount of energy required for the molecule to break free from the liquid phase.
In terms of solubility, its solubility varies in organic solvents. Due to the presence of bromine atoms and pyridine rings, this compound has a certain polarity. In polar organic solvents, such as dichloromethane and chloroform, it has good solubility due to the principle of "similar miscibility". However, in water, although the pyridine ring can form hydrogen bonds with water, the hydrophobicity of bromine atoms and bromomethyl groups limits their dissolution in water, so their solubility in water is not good.
In addition, its density is also an important property. The density depends on the weight of the molecule and the degree of intermolecular packing. 2-Bromo-3 - (bromomethyl) pyridine molecules contain bromine atoms. The relative atomic weight of bromine atoms is large, resulting in an increase in molecular weight. The spatial arrangement of the molecular structure makes the molecular packing relatively close, so its density is higher than that of common organic compounds.
In summary, the physical properties of 2-bromo-3- (bromomethyl) pyridine are determined by its molecular structure, and are also closely related to its application in organic synthesis, medicinal chemistry and other fields.

2-Bromo-3- (bromomethyl) pyridine is also an organic compound. When storing and transporting it, many matters need to be paid attention to.
The first priority is safety, and this compound is dangerous. When storing, it should be placed in a cool, dry and well-ventilated place. Due to the activity of bromine, high temperature and humid environment, it is easy to cause chemical reactions, or damage the purity of the substance, or even cause safety accidents. The warehouse temperature should be controlled within an appropriate range to prevent the compound from deteriorating due to excessive temperature.
Furthermore, attention should be paid to its isolation from other substances. 2-Bromo-3- (bromomethyl) pyridine should not be stored and transported with oxidants, strong bases, etc. Oxidants may react violently; contact with strong bases may also cause uncontrollable chemical changes, so be sure to store and transport it separately.
Packaging is also crucial. Appropriate packaging materials must be used to ensure its sealing and stability. Packaging should be able to withstand a certain amount of external force to prevent material leakage caused by package damage during transportation. Packaging materials must not react with the compound to avoid affecting its quality.
During transportation, the speed should be stable to avoid violent actions such as sudden braking and sharp turning to prevent package collision damage. Transport personnel should also be familiar with its characteristics and emergency treatment methods. In case of leakage and other situations, they can quickly and properly dispose of it to reduce harm.
Storage and transportation of 2-bromo-3- (bromomethyl) pyridine requires careful consideration of all details to ensure safety and material integrity.

I look at your question, but I am inquiring about the market price of 2-bromo-3- (bromomethyl) pyridine. Sadly, the market value of this chemical product is difficult to determine. Because the market situation changes rapidly, the price is determined by many factors.
The abundance of its raw materials is the key. If the raw materials are easily available and the price is flat, the cost of this product may decrease, and the market price will also decrease. On the contrary, the raw materials are rare and expensive, and the price will rise. Furthermore, the production skills also have an impact. Advanced methods can increase the yield and reduce losses, which is beneficial to the price. If the process is outdated, the cost is high and the price is difficult to be close to the people.
The supply and demand of the market also affect its price. If there are many people in need and there are few suppliers, the price will be high; if the supply exceeds the demand, the price will fall. There is also market competition. There are many merchants and fierce competition. In order to occupy the market, or reduce prices to attract customers.
In addition, policies and regulations, transportation costs, are also related to price changes. Policies encourage or reduce taxes, prices or drop; transportation is long and the cost is high, and the price also increases.
Due to the above factors, the market price of 2-bromo-3- (bromomethyl) pyridine is difficult to determine. If you want to know the price, you need to check the current market conditions, consult the merchants, and compare their quotations to obtain a more accurate number.
