The synthesis of 3-bromo-5- (chloromethyl) pyridine hydrochloride requires several steps of delicate chemical handling. First, a suitable pyridine derivative is used as the starting material, and a good reaction environment is selected, often in an organic solvent, to react with the brominating reagent. This bromination step requires careful inspection of the amount of reagent, reaction temperature and length. Usually, brominating reagents such as liquid bromine or N-bromosuccinimide (NBS) can introduce bromine atoms at a specific position in the pyridine ring, that is, position 3.
After the 3-bromopyridine derivative is obtained, it is then reacted with the reagent containing chloromethyl. In this process, chloromethylation reagents may be used, such as a mixed system of formaldehyde and hydrogen chloride, or other equivalent chloromethylation reagents. During the reaction, the reaction conditions must be regulated to ensure that chloromethyl is selectively attached to the 5 position of the pyridine ring. Among them, the nature of the solvent, the reaction temperature and pH are all key factors, which affect the process of the reaction and the purity of the product.
In addition, after the reaction is completed, the product may be 3-bromo-5- (chloromethyl) pyridine in a free state. At this time, to obtain the form of hydrochloride, it can be reacted with hydrogen chloride gas or hydrochloric acid solution, and under appropriate conditions, the free base can be converted into hydrochloride. This conversion process also needs to pay attention to the control of conditions to obtain high-purity 3-bromo-5- (chloromethyl) pyridine hydrochloride. After each step of the reaction, suitable separation and purification methods, such as column chromatography, recrystallization, etc., are required to remove impurities, improve the purity and quality of the product, and obtain the target product with good purity.

3-Bromo-5- (chloromethyl) pyridine hydrochloride is a chemical substance, and many things need to be paid attention to when storing. This substance has certain chemical activity and is quite sensitive to environmental conditions.
First, it should be placed in a cool place. High temperature can easily cause its chemical structure to change, or cause decomposition reactions. When it is hot, it must not be stored in direct sunlight or high temperature places. It should be stored in a well-ventilated and stable temperature cool warehouse.
Second, be sure to keep it dry. Because it may react with water, humid environment will cause deterioration. In case of rainy weather, pay more attention to moisture-proof in the warehouse, and a desiccant can be placed to maintain the dry environment.
Third, it needs to be stored separately from other chemical substances. This substance may react chemically with certain oxidizing agents, reducing agents or alkalis, etc., causing danger. If it cannot be placed in the same place as strong oxidizing agents, it will not cause violent reactions.
Fourth, choose the right storage container. A well-sealed container should be used to prevent it from deteriorating in contact with air. And the container material should be compatible with it. For example, containers cannot be made of materials that will react with the substance.
Fifth, do a good job of marking. Mark the name, characteristics and precautions of the substance in a prominent position at the storage place so that personnel can know and avoid misoperation.
The stability and safety of 3-bromo-5- (chloromethyl) pyridine hydrochloride during storage can only be ensured by following the above storage guidelines carefully.

3-Bromo-5- (chloromethyl) pyridine hydrochloride, the price of this product in the market is difficult to hide. The change in its price depends on multiple ends.
First, the amount of production is one of the reasons. If there are many people who produce this, the market is full of goods, and the supply exceeds the demand, the price may become more affordable. On the contrary, if there are few producers, the supply is scarce, and the supply is in short supply, the price will rise.
Second, the price of the material is also related. The fluctuation of the price of the materials required for the synthesis of this agent directly affects the cost of this product. If the price of the material rises, the price of the finished product will also rise; if the price of the material decreases, the price may decrease.
Furthermore, the new technology also affects its price. If the new technology is developed, the synthesis method will be simpler and cheaper, and the yield will also increase, and the price may decrease accordingly. However, if the technology does not progress, the synthesis will be difficult, the cost will be high, and the price will be difficult to drop.
In addition, the demand of the market is also the main reason. If the industry needs this, such as pharmaceuticals, chemical industries and other fields are thirsty, the price may be strong, or even higher. If the demand is low, the price will easily fall.
In summary, the market price of 3-bromo-5 - (chloromethyl) pyridine hydrochloride is capricious, and it is necessary to look at the production, materials, technology, and needs before we can know its general outline. If you want to know the real-time price, you can consult the price of the industry, the city manager or the trading platform.
