The method of preparing 2-chloro-3,6-dibromopyridine has been explored by many scholars in the past. One method is to start with pyridine. First, pyridine and bromine interact under appropriate reaction conditions, and bromine undergoes electrophilic substitution reaction on the pyridine ring. The electron cloud distribution of the pyridine ring has its own characteristics. The presence of nitrogen atoms reduces the electron cloud density of the pyridine ring, and the electron cloud density of the α and γ positions is relatively higher than that of the β position. Therefore, bromine has priority over the α and γ positions, and 3,6-dibromopyridine can be obtained. This step requires attention to control the reaction temperature, the amount of bromine and the reaction time to prevent excessive bromination. < Br >
After 3,6-dibromopyridine is obtained, it is then reacted with chlorination reagents, such as common chlorination reagents such as phosphorus oxychloride. Under suitable catalyst and reaction environment, chlorination occurs, and chlorine atoms are substituted for hydrogen atoms in specific positions in 3,6-dibromopyridine, and finally 2-chloro-3,6-dibromopyridine is obtained. In this process, factors such as the choice of catalyst and the pH of the reaction system have an important impact on the reaction process and product yield.
There is another method, using derivatives containing pyridine structures as starting materials, through multi-step reactions, chlorine atoms and bromine atoms are gradually introduced. For example, the derivative is first functionally converted to activate the pyridine ring at a specific position, which is convenient for the introduction of subsequent halogen atoms. After a series of carefully designed reaction steps, the purpose of preparing 2-chloro-3,6-dibromopyridine can also be achieved. However, there are many steps in this way, and the control of the reaction conditions is more stringent. Careful operation is required to strive for the efficiency and accuracy of each step of the reaction in order to improve the purity and yield of the product.

2-Chloro-3,6-dibromopyridine, the price of this product varies from time to time, and it also changes with quality and quantity. Looking at the various products described in "Tiangong Kaiwu" in the past, the price is subject to multiple systems. As far as 2-chloro-3,6-dibromopyridine is concerned, first, the difficulty of preparation is related to cost. If the production method is complicated, multiple doses are required, and labor-consuming, the price must be high. Second, the trend of supply and demand is necessary. If there are many people in the market, but there are few producers, the price will rise; on the contrary, if the supply exceeds the demand, the price may drop. Third, the quality is also heavy. Pure and miscellaneous, the price is often better than inferior products.
The common 2-chloro-3,6-dibromopyridine in the city, if the quantity is small and the quality is pure, the price may be between tens and hundreds of yuan in grams. If you buy in bulk, the larger the quantity, the price per unit may drop slightly. However, the price of chemical raw materials often fluctuates due to the price of raw materials, policy regulations, and changes in the current situation. Therefore, if you want to know the exact price, you should consult the chemical raw material supplier or observe the real-time market conditions to get a close price.
