Second, starting from the construction of the pyridine ring. Small molecule compounds containing trifluoromethyl and potential cyanyl functional groups are selected to construct the pyridine ring through cyclization reaction. For example, a specific β-ketone ester derivative and a nitrile compound containing trifluoromethyl are used to form the pyridine ring through multi-step reaction under a basic catalyst and a suitable temperature, and then the target product is obtained through subsequent modification. This route requires in-depth understanding of the conditions and mechanisms of cyclization to ensure the accuracy and yield of pyridine ring construction.
Third, the cross-coupling reaction catalyzed by transition metals. Select suitable pyridine derivatives, each with functional groups that can be cross-coupled with cyano and trifluoromethyl reagents, such as halogen atoms or borate ester groups. Under the catalysis of transition metal catalysts such as palladium and nickel, the coupling reaction is carried out with the corresponding cyanylation reagents and trifluoromethylation reagents.

5-Cyano-2-trifluoromethylpyridine is a unique organic compound with profound physical properties, which are described in ancient Chinese.
This substance often appears as a colorless to pale yellow liquid in appearance. It looks like a clear spiritual liquid, which is ubiquitous and shimmering under the light, with a hidden rhyme. It has a certain volatility, smells it lightly, and has a unique breath. However, it cannot be smelled for a long time to prevent damage to the body.
When it comes to the boiling point, it is about a specific range. This property allows it to gradually change from liquid to gaseous when heated moderately, just like the state of exuberance, from tangible to intangible gas, which permeates the space. The melting point also has its fixed number. When the external temperature drops to a certain critical point, it will change from a flowing state to a solidified body. For example, water condenses into ice on a cold night. Although the shape changes, the essence remains unchanged.
Its density is slightly different from that of water. If it is juxtaposed with water, or floats on it, or sinks on it, this is due to its specific gravity compared with water. And in terms of solubility, in many organic solvents, there are different degrees of miscibility, such as with alcohols, ethers, etc., which seem to attract and dissolve, and can be fused into one, indistinguishable from each other; while in water, the solubility is relatively limited, just like the separation between oil and water, although in the same place, it is difficult to form a unified.
The physical properties of 5-cyano-2-trifluoromethylpyridine are important in many fields such as organic synthesis. They are the key elements of many chemical processes, just like the ingenious tools in the hands of craftsmen.

Today there are 5-hydroxyl-2-trifluoromethyl pyridine, what is the price in the market?
The determination of the price of the husband is related to various reasons. First, the trend of supply and demand is the most important. If this 5-hydroxyl-2-trifluoromethyl pyridine has a large number of applicants and a small number of suppliers, the price will rise; on the contrary, if the supply exceeds the demand, the price will decline.
Second, the difficulty of its production also depends on the price. If the production of this 5-hydroxyl-2-trifluoromethyl pyridine requires delicate methods, rare materials, and harsh conditions, resulting in high costs and high prices; if the production method is simple and the materials are easy to obtain, the price may be close to the people.
Third, the competition in the city also affects the price. The partners of this 5-hydroxyl-2-trifluoromethyl pyridine in the city compete with each other, and the price will drop in order to compete for customers; if the camp is rare and almost exclusive, the price can be high.
Fourth, changes in the current situation and regulations of government can also make the price move. In case of bad luck, difficult business travel, or strict government regulations, increasing taxes, restricting production and sales, the price may be different from usual.
However, I do not know the details of the current situation of 5-hydroxyl-2-trifluoromethyl pyridine in the city, and it is difficult to determine its price. To know the exact price, you can consult the people in Jia, the industry, or the market report in the city.

5-Hydroxy-2-trifluoromethylpyridine, an organic compound, has a variety of related chemical reactions.
In nucleophilic substitution reactions, the hydroxyl group of 5-hydroxyl-2-trifluoromethylpyridine can be used as a nucleophilic check point. When encountering electrophilic reagents, such as halogenated alkanes, the oxygen atom of the hydroxyl group will attack the carbon atom of the halogenated alkane with its lone pair of electrons, and the halogenated atom will leave as a leaving group to form ether compounds. The reaction mechanism is that the nucleophilic reagent attacks the electrophilic center and forms a new chemical bond after undergoing a transition state.
In the oxidation reaction, the hydroxyl group of 5-hydroxy- 2-trifluoromethylpyridine can be oxidized by an oxidizing agent. If a suitable oxidizing agent is used, such as manganese dioxide or periodic acid, the hydroxyl group can be oxidized to a carbonyl group, which can be converted into a corresponding ketone compound.
