There are many ways to synthesize 2-chloro-5-cyanomethylpyridine. First, 2-chloro-5-methylpyridine can be used to start from 2-chloro-5-methylpyridine, and the methyl bromide can be obtained by bromination reaction. This step of the reaction usually uses N-bromosuccinimide (NBS) as the bromination reagent, and in the presence of an initiator such as benzoyl peroxide (BPO), the reaction is heated in a suitable solvent such as carbon tetrachloride. Then, 2-chloro-5-bromomethylpyridine is reacted with sodium cyanide or potassium cyanide in a polar aprotic solvent such as dimethylformamide (DMF), and the bromine atom is replaced by a cyano group to obtain 2-chloro-5-cyanomethylpyridine.
Furthermore, 2-chloro-5-hydroxymethylpyridine can also be used as a starting material. First, 2-chloro-5-hydroxymethylpyridine is reacted with p-toluenesulfonyl chloride to convert the hydroxyl group into a p-toluenesulfonate ester group. This reaction is carried out in the presence of an organic base such as pyridine. The resulting 2-chloro-5-p-toluenesulfonyloxymethyl pyridine is then reacted with a cyanide reagent, such as sodium cyanide, and the p-toluenesulfonate group is replaced by a cyano group to obtain the target product 2-chloro-5-cyanomethylpyridine.
Or, start with 2-chloro-5-aldehyde pyridine. First reduce the aldehyde group to hydroxymethyl, and choose a reducing agent such as sodium borohydride to react in an alcohol solvent such as methanol. The subsequent steps are similar to the method using 2-chloro-5-hydroxymethylpyridine as raw material, first converting to p-toluenesulfonate group, and then reacting with cyanide reagent to obtain the target. All methods have their own advantages and disadvantages, and the actual synthesis needs to be carefully selected according to the availability of raw materials, reaction conditions, cost and other factors.

2-Chloro-5-cyanomethylpyridine is one of the organic compounds. Its physical properties are unique. Looking at its appearance, at room temperature, it is mostly a colorless to light yellow liquid, which is bright and easy to identify.
When it comes to odor, it often emits a special smell, but it is not pungent and unpleasant, but has certain characteristics. This smell is also an important basis for identifying this substance.
Its boiling point is also a key physical property. After many experiments, its boiling point is within a certain range. The characteristics of this boiling point can be an important guide when separating, purifying and related chemical operations. When heated to this specific temperature, the state of the substance changes from liquid to gaseous state. This change process follows the laws of physics. According to its boiling point, it can be used for actual production.
Furthermore, the melting point cannot be ignored. The value of the melting point represents the critical temperature for the transformation from solid to liquid. Knowing the melting point of this substance can be properly disposed of according to the ambient temperature during storage, transportation and processing to ensure the stability of the substance.
As for solubility, 2-chloro-5-cyanomethylpyridine exhibits good solubility in organic solvents. Common organic solvents, such as ethanol and acetone, are soluble with it, but their solubility in water is relatively limited. The difference in solubility is due to the interaction between its molecular structure and solvent molecules. In chemical synthesis and reaction system construction, it is an important consideration for selecting suitable solvents.
Density is also one of its physical properties. Its density is specific and has a unique value compared with other substances. In the measurement, mixing and other operations of chemical production, the accurate knowledge of density is related to the quality of the product and the accuracy of the reaction.
In summary, the physical properties of 2-chloro-5-cyanomethylpyridine, such as appearance, odor, boiling point, melting point, solubility, and density, are of indispensable significance in the study of organic chemistry and the practice of chemical production. It is also necessary for practitioners in related fields to know in detail.

2-Chloro-5-cyanomethylpyridine is one of the chemical substances. During storage and transportation, many matters need to be paid attention to.
When storing, the first environment. It should be placed in a cool, dry and well-ventilated place. This is because the substance may be sensitive to temperature and humidity, high temperature and humid environment, it may cause its qualitative change. For example, if in a humid place, moisture may react with the substance, causing its chemical structure to change and lose its original characteristics.
Furthermore, it should be stored separately from oxidizing agents, acids, bases, etc. Due to its active chemical properties, it may mix with them, or cause violent chemical reactions, or even cause the risk of explosion. If the oxidizing agent has strong oxidizing properties, it may meet with 2-chloro-5-cyanomethylpyridine, which may cause combustion or explosion.
Packaging should not be ignored. Sealed packaging is required to ensure that there is no risk of leakage. High-quality packaging materials can prevent material volatilization, deliquescence, and ensure its stability.
When transporting, drivers and escorts must be familiar with the characteristics of the substance and emergency treatment methods. Transportation vehicles should be equipped with corresponding fire protection equipment and leakage emergency treatment equipment. During driving, avoid high temperature and open flames.
The loading and unloading process should be handled lightly to prevent packaging damage. If the packaging is damaged, the material leaks, which not only pollutes the environment, but also threatens the safety of personnel. When storing and transporting 2-chloro-5-cyanomethylpyridine, all steps must be handled with caution and in accordance with regulations to ensure personnel safety and material stability.

The market price range of 2-chloro-5-cyanomethylpyridine is difficult to determine. This is due to the fickle market conditions, and the price varies with many factors.
First, the price of raw materials has a great impact. If the starting material required for the synthesis of this compound is in short supply or the production cost rises, the price of 2-chloro-5-cyanomethylpyridine will rise. On the contrary, the supply of raw materials is abundant and cheap, and its price is expected to decline.
Second, market supply and demand are also key. If there is a strong demand for 2-chloro-5-cyanomethylpyridine in many industries, such as medicine, pesticides and other fields, the R & D and production rely heavily on this product, and the supply is difficult to meet the demand for a while, the price will be high; if the demand is sluggish and the supply exceeds the demand, the price will decline.
Third, the preparation process is also related to the price. If a new process emerges, it can improve production efficiency, reduce energy consumption and costs, and the price may be reduced accordingly; however, if the process is complex and requires high-end equipment and technology, the cost will remain high and the price will be difficult to drop.
Fourth, policies and regulations and the international trade situation cannot be ignored. Stricter environmental protection policies may lead to production restrictions and increased costs; trade frictions, tariff adjustments, etc., will interfere with product circulation and prices.
To sum up, in order to determine the market price range of 2-chloro-5-cyanomethylpyridine, it is necessary to pay attention to the raw material market, supply and demand dynamics, process progress and policy and trade changes in real time. Only through detailed research and analysis can we accurately grasp, and it is difficult to give the exact price range at this moment.
