3-(bromomethyl)pyridine hydrobromide (1:1)

3- (bromomethyl) pyridine hydrobromide (1:1), is one of the organic compounds. It has unique chemical properties.
Looking at its structure, it contains a pyridine ring, with bromomethyl at the third position on the ring, and forms a salt with hydrobromic acid. This structure gives it special chemical activity. In terms of physical properties, it is often solid and has a certain melting point and solubility. In organic solvents, its solubility varies depending on the properties of the solvent. If it is in polar organic solvents, it may have good solubility, but because the molecule is polar, it can interact with polar solvents.
In terms of its chemical activity, bromomethyl is extremely active. Nucleophilic substitution reaction can occur, because the bromine atom is easy to leave, the nucleophilic test agent can attack its carbon site, resulting in the formation of substitution products. The nitrogen atom of the pyridine ring has a lone pair of electrons, which can be used as a nucleophilic check point to participate in nucleophilic addition or catalytic reactions. The hydrobromate part, under appropriate conditions, can release protons, make the compound acidic, and participate in acid-base related reactions.
In addition, the stability of the compound also needs attention. When exposed to certain chemical substances at a specific temperature, light or contact, it may decompose or deteriorate. Due to its active chemical properties, appropriate measures should be taken during storage and use to prevent its properties from changing and ensure that it can play its intended role in chemical synthesis and other fields.

3- (bromomethyl) pyridine hydrobromide (1:1) is a common compound in organic synthesis. The synthesis method has been investigated by predecessors, and the common ones mentioned above are as follows.
One is to use pyridine as the starting material, and under suitable reaction conditions, pyridine can be co-reacted with brominating reagents and methylating reagents. For example, using N-bromosuccinimide (NBS) as the bromination source, combined with an appropriate initiator, such as benzoyl peroxide (BPO), under the condition of heat or light, the specific position of pyridine can be bromomethylated, and then the target product can be formed. The key to this reaction lies in the precise control of the reaction conditions. Temperature, light intensity, and the dosage ratio of reagents all have a significant impact on the yield and selectivity of the reaction. If the temperature is too high, or the amount of initiator is too high, it is easy to cause side reactions such as excessive bromination, which will reduce the purity and yield of the target product.
The second is to modify the pyridine to form a specific pyridine derivative, and then carry out the bromomethylation reaction. For example, the nitrogen atom of the pyridine is first alkylated to form a quaternary ammonium salt to change the electron cloud distribution of the pyridine ring and enhance its reactivity and selectivity. Subsequently, suitable bromomethylation reagents, such as bromochloromethane, are selected to react under alkaline conditions to obtain the target product. The advantage of this approach is that the pre-modification of the pyridine ring can precisely regulate the reaction check point and activity, and improve the controllability of the reaction. However, the process is more complicated, requiring multiple steps of reaction, and requires high reaction operation and purification.
The third is the method of catalysis with transition metals. Using transition metals such as palladium and copper as catalysts, with specific ligands, pyridine and bromomethyl-containing reagents can be coupled under mild reaction conditions. This method has the advantages of mild reaction conditions and high selectivity, which can effectively avoid the side reactions caused by high temperature or strong reagents in traditional methods. However, the cost of transition metal catalysts is high, and the separation and recovery of catalysts after reaction is difficult, which limits their large-scale industrial application to a certain extent.
The above synthesis methods have their own advantages and disadvantages. In practical applications, it is necessary to weigh and choose the appropriate synthesis path according to specific needs, raw material availability, cost considerations and other factors, in order to achieve efficient, economical and environmentally friendly synthesis goals.

I think this "3 - (bromomethyl) pyridine hydrobromide (1:1) " is a chemical product. Its market price is difficult to determine, due to many factors.
First, the purity of this product is the key to affecting the price. If the purity is extremely high, it is almost flawless, and the price is high; if it contains impurities, the price is slightly reduced. And the preparation of this compound with high purity is complicated, and the cost also rises, which naturally increases the price.
Second, the state of market supply and demand also affects the price. If there are many people in the market, but the supply is small, the so-called "rare is expensive", the price will rise; on the contrary, if the supply is full and the demand is weak, the price will decline.
Third, the price of raw materials and the method of preparation have a great impact on the cost. If the raw materials required for preparation are scarce and expensive, or the preparation process is cumbersome, it requires a lot of resources, and the cost is high, the price of the finished product is also difficult to lower.
Fourth, the difference between manufacturers and regions also makes the price different. Different manufacturers have their own pricing differences due to different technical levels and operating costs. And different regions, transportation costs, tax policies and other factors can make the price change.
However, roughly speaking, in the current market, if it is of ordinary purity, the price per gram may be around tens of yuan to 100 yuan; if it is a high-purity boutique, the price per gram may exceed 100 yuan, or even higher. This is only a rough estimate, and the actual price depends on the specific market conditions.

3 - (bromomethyl) pyridine hydrobromide (1:1) is also a chemical substance. During storage and transportation, many precautions should not be ignored.
First words storage, this substance should be placed in a cool, dry and well-ventilated place. Because of the cool environment, it can prevent it from changing its properties due to excessive temperature or causing dangerous reactions. Dry environment can avoid moisture, which may affect its chemical properties or even deteriorate. Well-ventilated, it can disperse harmful gases that may be volatile in time and keep the storage space safe.
Furthermore, it must be stored separately from oxidants, strong alkalis and other substances. The oxidizing agent has strong oxidizing properties, or a violent oxidation reaction occurs with the substance; the chemical properties of strong bases are active, and it may also react chemically with 3- (bromomethyl) pyridine hydrobromide (1:1), causing it to deteriorate and even cause danger.
As for transportation, be sure to ensure that the packaging is complete and sealed. The packaging is complete to prevent material leakage; well sealed to avoid contact with outside air, moisture, etc. During transportation, the driving should be stable to avoid vibration and impact. Due to vibration and impact or damage to the packaging, and may cause physical or chemical reactions inside the substance, endangering transportation safety.
In addition, transport personnel should be familiar with the characteristics of the substance and emergency treatment methods. In the event of an emergency such as a leak, it can be responded to quickly and correctly, and the harm can be minimized. In short, all aspects of the storage and transportation of 3 - (bromomethyl) pyridine hydrobromide (1:1) need to be carefully handled to ensure safety.
