The synthesis of methyl-2,3,5,6-tetrachlorosulfonyl-pyridine is a key research topic in the field of organic synthetic chemistry. This compound has important application value in many fields, such as medicinal chemistry, materials science, etc. The following are several common synthesis methods:
First, pyridine is used as the initial raw material. Pyridine is first halogenated, usually chlorine gas or chlorine-containing reagents are used. Under suitable reaction conditions, chlorine atoms are introduced at specific positions on the pyridine ring to form polychloropyridine derivatives. Subsequently, using sulfonylation reagents, such as chlorosulfonic acid or sulfonyl chloride, the sulfonyl group is introduced into the polychloropyridine derivative, and through a series of reaction conditions, the target product methyl-2,3,5,6-tetrachlorosulfonylpyridine can be obtained. The advantage of this route is that pyridine raw materials are relatively common and come from a relatively wide range of sources. However, the halogenation and sulfonylation steps require precise control of the reaction conditions to ensure the selectivity and purity of the product.
Second, select the appropriate substituted pyridine derivative as the starting material. If the starting material already contains some of the desired substituents, the reaction steps can be reduced. By rationally designing the reaction route, the starting material is modified first, or through nucleophilic substitution, electrophilic substitution and other reactions, chlorine atoms and sulfonyl groups are gradually introduced, and finally the synthesis of methyl-2,3,5,6-tetrachlorosulfonyl pyridine is achieved. This strategy can improve the reaction efficiency, but the selection and preparation of starting materials are quite high, and specific synthesis methods are required to obtain suitable starting materials.
Third, the reaction is catalyzed by transition metals. Transition metal catalysts such as palladium and copper exhibit unique catalytic properties in organic synthesis. Transition metals can be used to catalyze the coupling reaction of halogenated pyridine and sulfonyl-containing reagents to construct the structure of the target product. Such methods can often be carried out under milder reaction conditions, and have good regioselectivity and functional group compatibility. However, the cost of transition metal catalysts is high, and the post-reaction treatment needs to consider issues such as catalyst separation and recovery.
There are various methods for synthesizing methyl-2,3,5,6-tetrachlorosulfonyl pyridine, each with its own advantages and disadvantages. Researchers need to carefully select suitable synthesis routes according to their own experimental conditions, raw material availability and product requirements, in order to achieve an efficient, economical and environmentally friendly synthesis process.

Methyl-2,3,5,6-tetrachlorosulfonylpyridine This substance has unique physicochemical properties. It is a solid and has good stability at room temperature. In water, the solubility is quite low, but it can be soluble in various organic solvents, such as ethanol and acetone. Because the polar groups in the structure and the organic solvent can form intermolecular forces, its solubility is increased.
Looking at its melting point, it is about a specific range, which is determined by intermolecular forces and lattice energy. When heated to the melting point, the lattice breaks and the substance melts. The boiling point also has a specific value. When it reaches the boiling point, the molecule can get enough energy to break free from the liquid phase and turn into the gas phase.
This substance is chemically active, and the sulfonyl group has strong electrophilicity, which is easy to react with nucleophilic reagents. The electron cloud distribution of the pyridine ring makes its neighbor and para-position vulnerable to electrophilic reagents. In the organic synthesis channel, it is often used as a key intermediate. With its activity, it reacts with various reagents to prepare nitrogen-containing heterocyclic compounds or organics with special functional groups. It is widely used in the fields of medicine, pesticides and materials. Due to its unique physicochemical properties, it paves the way for the synthesis and creation of new substances, and also plays an important role in chemical production and scientific research.

The price range of methyl-2,3,5,6-tetrachlorosulfonylpyridine on the market is difficult to say exactly. This is due to the fickle market conditions, and the price of this product is affected by many factors.
The difficulty of its production process has a great impact on the price. If the production process is complicated, many fine steps and special technologies are required, and the raw materials used are scarce and difficult to find, the cost will be high, and the price will be high. On the contrary, if the process is relatively simple and the raw materials are easily available, the price may be slightly lower.
The state of market supply and demand is also the key. If there are many buyers, but the output is limited, and the supply is in short supply, the price will rise; if the market is oversupplied and the demand is small, the price will drop.
In addition, different merchants have different pricing strategies. There are small profits but quick turnover, pricing is close to the people; there are also strategies to take high prices based on brand and quality advantages.
Then check the past transaction records and market conditions. The price of this methyl-2,3,5,6-tetrachlorosulfonyl pyridine per gram may be between tens and hundreds of yuan. But it must not be a fixed number based on this. The market conditions are diverse, and the price often fluctuates with many variables. To know the exact price, you need to consult the relevant chemical product suppliers in detail before you can get the current exact quotation.

Methyl-2,3,5,6-tetrachlorosulfonylpyridine, this is a rather special chemical substance. Its storage conditions are of great importance, which is related to the stability and safety of its properties.
The cover must be stored in a cool and dry place due to its unique chemical activity. If placed in a warm and humid place, it may cause chemical reactions or deterioration to fail due to changes in temperature and humidity. Therefore, it is appropriate to choose a cool and dry place, such as a cellar or a special cool warehouse.
Furthermore, it should be kept away from fire sources and oxidants. This substance may be flammable and dangerous in case of fire; it also encounters with oxidants, which can easily trigger violent chemical reactions, or even cause explosions. Therefore, in the storage place, fireworks are strictly prohibited, and they are stored separately from oxidants to ensure safety.
In addition, the storage place should be well ventilated. If the ventilation is not smooth, the volatile gas of this substance will accumulate, which is harmful to the environment on the one hand, and harmful to human health on the other. It is easy to cause safety accidents. Therefore, a good ventilation device must be set up to circulate the air and disperse the volatile gas.
Storage containers should also be selected carefully. Corrosion-resistant materials should be used. Containers made of ordinary materials are prone to erosion and risk leakage. Such as special glass containers or specific plastic containers, which can prevent leakage and ensure their safety.
In summary, the storage of methyl-2,3,5,6-tetrachlorosulfonyl pyridine should be in a cool, dry, well-ventilated place away from fire-source oxidants, and in a corrosion-resistant container, so as to ensure its quality and safety.
