The synthesis method of 3 - (bromomethyl) pyridine hydrobromide has been recorded in many books in the past, and these several common methods are mentioned.
First, 3-methylpyridine is used as the starting material. First, 3-methylpyridine is reacted with N-bromosuccinimide (NBS) in the presence of an initiator. Usually benzoyl peroxide (BPO) is used as the initiator, and it is heated and refluxed in a suitable solvent such as carbon tetrachloride. In this reaction, NBS provides the bromine source. Under the action of the initiator, the hydrogen on the methyl group of 3-methylpyridine is replaced by the bromine atom to generate 3 - (bromomethyl) pyridine. Subsequently, 3 - (bromomethyl) pyridine hydrobromide can be obtained by treatment with hydrobromic acid. This process requires attention to the reaction temperature. If the temperature is too high, side reactions will increase and the yield will decrease; if the temperature is too low, the reaction rate will be slow.
Second, 3 - pyridine methanol is used as the starting material. 3 - pyridine methanol first reacts directly with hydrobromic acid, and the bromine ion in the hydrobromic acid replaces the alcohol hydroxyl group to undergo a nucleophilic substitution reaction to generate 3 - (bromomethyl) pyridine. Continue to react with excess hydrobromic acid to obtain the target product 3 - (bromomethyl) pyridine hydrobromide. This method is more direct, but attention should be paid to the control of the acidity of the reaction system. If the acidity is not correct, other side reactions may occur in the pyridine ring, which will affect the purity and yield of the product.
Third, the corresponding pyridine derivatives are used as raw materials to construct the bromomethyl structure through multi-step reaction. For example, the pyridine ring is properly modified first, and a group that can be converted to bromomethyl is introduced, and then converted through a specific reaction. Although there are many steps, this method is an effective means for some synthesis that requires harsh reaction conditions and specific structural requirements. The reaction conditions of each step need to be carefully controlled during operation to ensure the smooth progress of each step and improve the yield and purity of the final product.

3 - (bromomethyl) pyridine hydrobromide is a chemical substance, and many matters need to be paid attention to during storage and transportation.
First word storage. This substance should be placed in a cool, dry and well-ventilated place. Because of the cool environment, it can avoid its biological change due to excessive temperature; dry place, it can prevent it from moisture, if it is damp, it may cause its chemical properties to change, affecting the use. Good ventilation is also essential to prevent the accumulation of harmful gases. And it must be stored separately from oxidants, strong bases and other substances. Oxidants are highly oxidizing, or react violently with 3- (bromomethyl) pyridine hydrobromide; strong bases may also react chemically with it, damaging its quality. The storage place should be clearly marked, so that people can know what it is at a glance, so as to prevent misuse.
Let's talk about transportation again. When transporting, the packaging must be tight. Appropriate packaging materials should be selected to ensure that during transportation, the packaging will not be damaged due to bumps and collisions, causing material leakage. The transportation vehicle should also be clean, dry, and free of other residual substances that may react with it. Transport personnel must be professionally trained to be familiar with the characteristics of this substance and emergency treatment methods. If an accident such as a leak occurs during transportation, they can respond quickly and correctly to reduce the harm. During transportation, pay attention to changes in temperature and humidity to avoid adverse effects from extreme environments. In short, the storage and transportation of 3- (bromomethyl) pyridine hydrobromide should be done with caution and strict compliance with regulations, so as to ensure complete security.

I don't know what the market price range of "3 - (bromomethyl) pyridine hydrobromide" is. Because the market price is often affected by many factors, such as raw material cost, production process, market supply and demand, regional differences, quality specifications, etc.
If the raw materials are easy to obtain and low cost, the production process is simple and mature, the market supply is sufficient and the demand is relatively stable, the price may be relatively close to the people. However, if the raw materials are scarce, the production is difficult, and the market demand is strong, the price will be high.
And depending on the region, the economic level, transportation costs, tax policies, etc. vary from place to place, which will also cause the price to fluctuate. The quality specifications are different, those with fine purification and high purity must be higher than those with ordinary specifications.
To know the exact market price range, you can obtain accurate price information by carefully checking the chemical product trading platform, consulting chemical raw material suppliers, referring to industry reports or researching recent market transaction records.
