To prepare 6-fluoro-3-hydroxy-2-bromopyridine, there are two common methods.
One is to use the compound containing the pyridine ring as the starting material, and to prepare it by reaction of halogenation and hydroxylation. If 3-hydroxypyridine is used as the starting point and the bromine atom is introduced before the second position of the pyridine ring, the 3-hydroxypyridine can be dissolved in a suitable solvent, such as dichloromethane, cooled to a low temperature, such as 0 ° C, slowly add a brominating agent, such as N-bromosuccinimide (NBS), and add an initiator, such as azobisisobutyronitrile (AIBN). Under these conditions, the bromine atom will selectively replace the hydrogen at the second position of the pyridine ring to obtain 2-bromo-3-hydroxypyridine. Then, fluorine atoms are introduced, and the product is combined with fluorinated reagents, such as potassium fluoride, in a high-boiling polar solvent, such as dimethyl sulfoxide (DMSO), and the reaction is heated at high temperature. The fluorine atom replaces the halogen or other leaving groups in the appropriate position to obtain 6-fluoro-3-hydroxy-2-bromopyridine.
The second strategy is to construct a pyridine ring. The pyridine ring structure can be constructed by cyclization of compounds containing carbonyl, amino and halogen atoms. If β-ketone ester, ammonia source and halogen are used as raw materials, β-ketone ester is first reacted with ammonia source to form a pyridine ring precursor. This process may need to be carried out at an appropriate temperature and in the presence of a catalyst. After that, the obtained pyridine ring precursor is halogenated and hydroxylated. If fluorine atoms are introduced first, nucleophilic substitution reaction can be used, and then bromine atoms and hydroxyl groups can be introduced at an appropriate position. The specific reaction conditions need to be carefully adjusted according to the selected raw materials and reaction activities. 6-fluoro-3-hydroxy-2-bromopyridine can also be obtained through multi-step reaction.

6-Fluoro-3-hydroxy-2-bromopyridine, the price of this product in the market is geometric, and it is difficult to judge. The change in its price is related to various reasons.
The first is the situation of supply and demand. If there is a booming field, such as pharmaceutical research and development, fine chemicals, etc., there is a strong demand for this product, but there are few producers and scarce supply, then the price will rise. On the contrary, if the supply exceeds the demand and the market is full, the price may decline.
Furthermore, the price of raw materials is also the key. The cost of 6-fluoro-3-hydroxy-2-bromopyridine will increase, and the price will also rise.
The process is difficult and easy, which also affects its price. If the preparation method is complicated, requires high-precision technology and expensive equipment, and the yield is not high, the loss is quite large, and its price is not cheap.
The origin and quality are also the main reasons. Different origins, due to differences in terroir and skills, may have different quality. The superior one is usually the highest; the inferior one is slightly lower.
In the past, the price of chemical substances often fluctuated with changes in the market. 6-Fluoro-3-hydroxy-2-bromopyridine is also difficult to escape this law. To know its exact price, it is advisable to consult a chemical material supplier or visit a professional trading platform to obtain a real-time and accurate price to meet the needs.

6-Fluoro-3-hydroxy-2-bromopyridine is a kind of organic compound. Its storage conditions are quite important, which is related to the stability and quality of this compound.
This compound should be stored in a cool, dry and well-ventilated place. In a cool environment, it can avoid decomposition or other chemical reactions caused by excessive temperature. High temperatures often accelerate the movement of molecules, making chemical bonds more susceptible to cracking, which in turn damages the structure and properties of the compound.
Dry conditions are also indispensable. The moisture in the air may react with 6-fluoro-3-hydroxy-2-bromopyridine, or cause adverse changes such as hydrolysis. Moisture can participate in many chemical reactions and change the chemical composition of compounds, so it is necessary to try to keep the storage environment dry.
Good ventilation is also key. If the storage space is poorly ventilated, volatile compound gases or accumulation will increase the risk of fire and explosion, and the second will cause pollution to the storage environment and affect the purity of the compound.
In addition, this compound should be stored separately from oxidants, acids, bases and other substances. Due to the chemical properties of 6-fluoro-3-hydroxy-2-bromopyridine, when it comes into contact with the above substances, or a violent chemical reaction occurs, resulting in dangerous conditions, such as combustion, explosion, etc.
When storing, follow relevant safety procedures and standards to ensure the safety of personnel and the environment. There are also requirements for storage containers. It is necessary to choose suitable materials, which can not only withstand the corrosion of compounds, but also effectively seal and prevent leakage. In this way, 6-fluoro-3-hydroxy-2-bromopyridine can be properly stored to maintain its good chemical properties and quality.
