pyridine, 2,6-dichloro-3-methyl-

"Tiangong Kaiwu" was written by Song Yingxing in the Ming Dynasty. At that time, there was no record of "pyridine, 2,6-dichloro-3-methyl -" such compounds. However, according to today's chemical knowledge, I can describe its physical properties in ancient classical style.
This "pyridine, 2,6-dichloro-3-methyl -", according to its name, can be seen to be related to pyridine and is an organic compound. It is often in a liquid state. Under normal temperature and pressure, it is nearly colorless or has a light color, just like the purity of clear water, but it is slightly different. Its taste is pungent, and the smell is like a spicy environment, which is difficult to smell for a long time.
The density of this substance is compared with water, or slightly greater than that of water. When placed in water, it seems that oil sinks to the bottom, and it does not melt and forms itself. The values of its boiling point and melting point are fixed, and the boiling point is higher. To make it boil, a higher temperature needs to be added, just like if you want to melt iron and stone, it cannot be formed without a strong fire; the melting point determines the temperature at which it changes from solid to liquid, such as ice melts when it is warm.
In terms of solubility, in organic solvents such as ethanol and ether, it is quite able to blend, just like a fish swimming freely in a river; however, in water, the solubility is not good, just like the contradiction between oil and water, it is difficult to mix.
Its volatility cannot be ignored. It is slowly emitted in the air. If the light smoke curls, it will change the surrounding atmosphere when it is emitted due to its pungent smell, which will be perceived by people. Although the physical properties of this compound are described in writing, it is hoped that its general nature can be clarified, so that the viewer can have a preliminary understanding of it.

Pyridine, 2,6-dichloro-3-methyl, is an important compound in organic chemistry. Its chemical properties are unique and have a variety of characteristics.
In terms of its physical properties, it is mostly a colorless to light yellow liquid with a special odor and is stable at room temperature and pressure. Its boiling point and melting point vary due to the presence of chlorine atoms and methyl groups in the molecular structure. The electronegativity of chlorine atoms is large, which enhances the intermolecular force and causes the boiling point to rise; the introduction of methyl groups changes the molecular space structure, affects the way of molecular accumulation, and also has an effect on the melting point.
Chemically, pyridine rings are aromatic. Due to conforming to the Shocker rule, they have a certain stability and can undergo electrophilic substitution reactions. However, because the electronegativity of nitrogen atom is greater than that of carbon atom, the electron cloud density distribution on the ring is uneven, and the electrophilic substitution reaction mostly occurs in the β-position (relative to the nitrogen atom). The substituent of 2,6-dichloro-3-methyl has a great influence on the reactivity and selectivity. The chlorine atom is an electron-withdrawing group, which reduces the electron cloud density of the pyridine ring and weakens the electrophilic substitution activity; the methyl group is a power supply group, which can increase the electron cloud density of the adjacent and para-position to a certain extent, which affects the selectivity of the reaction check point.
Furthermore, the chlorine atom in this compound can undergo nucleophilic substitution reactions. Under appropriate nucleophilic reagents and reaction conditions, chlorine atoms can be replaced to form new organic compounds, which is a common method for constructing carbon-heteroatom bonds in organic synthesis. At the same time, pyridine nitrogen atoms have lone pairs of electrons, which can be used as ligands to form complexes with metal ions, and have potential applications in the field of catalysis.

There are currently pyridine, 2,6-dichloro-3-methyl, and the synthesis method is as follows:
Starting material, take a suitable pyridine derivative as the base. First, the chlorination reaction is carried out with a chlorination reagent, such as a chlorine-containing halogenating agent, under suitable reaction conditions. To obtain the chlorination at the 2,6-position, the reaction environment needs to be carefully regulated, such as the choice of temperature, solvent and catalyst. Appropriate halogenation catalysts, such as certain metal halides, are selected to preferentially occur at the 2,6-position of the pyridine ring at a specific temperature range, and then chlorine atoms are introduced. < Br > Then, for the introduction of the 3-position methyl group, suitable methylating reagents can be selected, such as methyl halide or methylated organometallic reagents. In the presence of an appropriate base, the nucleophilic substitution reaction is carried out. The strength and dosage of the base need to be carefully controlled to ensure that the methylation reaction selectively occurs at the 3-position of the pyridine ring.
During the reaction process, it is appropriate to monitor the progress of each step of the reaction by means of thin-layer chromatography or gas chromatography, etc., and observe it in real time. After the reaction, the product needs to be separated and purified, such as column chromatography, recrystallization, etc., to obtain high-purity 2,6-dichloro-3-methylpyridine. In this way, according to the above steps and conditions, this compound may be synthesized.

What I'm asking you is about pyridine, 2,6-dichloro-3-methyl, which is in the market price range. However, the price of this product is difficult to say in a word.
The price of this product often varies due to many factors, the first being the price of raw materials. If the price of raw materials required for the synthesis of this pyridine derivative, such as chlorination reagents, methylation reagents, etc., fluctuates, it will affect the price of the final product. If the raw materials are abundant and cheap, the price of this pyridine may become stable and low; conversely, if the raw materials are scarce and the supply is insufficient, the price will rise.
Furthermore, the production process and cost are also key. Advanced and efficient technology can reduce energy consumption and increase productivity. The cost is low, and the price can be close to the people. If the process is backward, it consumes more and produces less, and the cost is high, the price will not be low.
The market supply and demand relationship also affects its price. If the market has strong demand for this product, such as in the fields of medicine and chemical synthesis, and the supply is limited, the price will rise; if the demand is low and the supply is excessive, merchants will sell their goods or reduce the price in order to sell.
In addition, the differences in regions and manufacturers also make the prices different. In different places, the price may vary due to different transportation costs and tax policies; each manufacturer has different pricing based on its own brand and quality control.
Overall, in order to determine the market price range of pyridine, 2,6-dichloro-3-methyl, it is necessary to carefully investigate the raw materials, processes, supply and demand, etc. Roughly speaking, the price may fluctuate between tens of yuan and hundreds of yuan per kilogram, depending on the actual market conditions.
