The synthesis method of 5-bromo-2-hydroxypyridine has been known for a long time. In the past, there was a method of halogenation based on pyridine. First, the pyridine was put in an appropriate solvent, met with brominating reagents such as bromine or bromine-containing compounds, controlled its temperature and adjusted its degree, and then bromopyridine was obtained. After that, the hydroxyl group was introduced. Or hydrolyzed with alkali, or by nucleophilic substitution, the bromine atom was replaced by a hydroxyl group.
There are also those who use other compounds as starting materials. If a specific halogenated aromatic hydrocarbon is combined with a nitrogen-containing nucleophilic reagent by a nucleophilic aryl substitution reaction to form the prototype of a pyridine ring, and then modified by halogenation, hydroxylation, etc., 5-bromo-2-hydroxypyridine is finally obtained.
Furthermore, organometallic reagents can also help. For example, lithium reagents or magnesium reagents can be used to interact with suitable halogenated pyridine derivatives to introduce a functional group of bromine atoms or hydroxyl groups. After a series of delicate transformations, the purpose of synthesis can also be achieved. The reaction steps are fine, and the control of the conditions of each step is crucial. The choice of solvent, the temperature, and the ratio of reactants are all crucial to success or failure. Repeated tests and consideration are required to obtain a pure product, resulting in the delicate synthesis of this chemistry.

5-Bromo-2-hydroxypyridine, in the market of chemical raw materials, its price often changes due to many reasons.
Watching the market conditions of the past, if the supply is full, the merchants compete to sell, the price may become easier. Because of oversupply, merchants want to sell their goods quickly in order to reduce the burden of warehousing, so they may lower their prices to attract customers.
However, if the raw materials are scarce, or the production method changes, resulting in a sharp decrease in output, the price will often rise. For example, if the bromide on which it depends is rare, or the synthesis process encounters obstacles, the output will not continue, and there are still many people who need it, and the demand is too high, and the price will be high. < Br >
Moreover, the market demand is also the main reason. If the demand for 5-bromo-2-hydroxypyridine in a certain industry increases greatly, such as the sudden rise in the pharmaceutical synthesis industry, the amount of 5-bromo-2-hydroxypyridine will increase sharply, and the price will also rise accordingly. On the contrary, if there is no new demand, only the regular demand will be maintained, and the price may be stable and decline.
Its price often fluctuates between tens of yuan and hundreds of yuan per kilogram. In the past, it has been seen that the price is around 50 yuan per kilogram, and it has also reached 300 or 400 yuan. Therefore, if you want to know the exact price, you need to observe the current market conditions and consult the business of chemical raw materials before you can get a near-real price.

5-Bromo-2-hydroxypyridine is also an organic compound. When storing and transporting, many matters must be paid attention to to to ensure its quality and safety.
First words storage. This compound should be placed in a cool, dry and well-ventilated place. Because the substance is quite sensitive to humidity and temperature, high temperature and humid environment can easily cause it to deteriorate. For example, if it is in a humid place, moisture may react with 5-bromo-2-hydroxypyridine, affecting its chemical properties. And it should be kept away from fire and heat sources, because it is flammable to a certain extent, it is at risk of encountering open flames, hot topics or causing combustion. At the same time, it needs to be stored separately from oxidants, acids, bases, etc. to prevent mutual reaction. This is because of the chemical structure of 5-bromo-2-hydroxypyridine, which makes it easy to cause chemical reactions when it comes into contact with the above substances, causing it to fail or produce dangerous products.
Second transportation. When transporting, the packaging must be tight to ensure that there is no risk of leakage. Choose suitable packaging materials to effectively resist the influence of the external environment. During transportation, the speed should not be too fast, and it should be driven smoothly to avoid bumps and vibrations to prevent damage to the packaging and cause leakage of 5-bromo-2-hydroxypyridine. Furthermore, the transport vehicle should be equipped with corresponding fire equipment and leakage emergency treatment equipment, in case of emergencies, can respond in time. The escort personnel also need to have professional knowledge, familiar with the characteristics of 5-bromo-2-hydroxypyridine, and closely monitor during transportation to ensure the safety of transportation.
