2-Chloro-3-iodopyridine, 98 +%, its physical properties are as follows: This substance is a solid at room temperature, and it appears to be a white to pale yellow crystalline powder. Its melting point ranges from about 46-48 ° C, which makes it undergo physical state transformation in a specific temperature range. The substance is almost insoluble in water, and its solubility in water is extremely low. However, it can be soluble in organic solvents such as dichloromethane, chloroform, ether, and tetrahydrofuran. This difference in solubility is due to the influence of chlorine and iodine atoms in the molecular structure, which makes it interact differently with different solvents. Its density is about 1.98 g/cm ³ according to relevant theoretical calculations and some experimental measurements. This density data is of great significance for considering its distribution in the solution system and the proportion of materials involved in the reaction. Because its molecule contains two halogen atoms, chlorine and iodine, it has certain stability. However, when it encounters specific chemicals such as strong oxidants and strong bases, it will also undergo chemical reactions and change its physical properties.

2-Chloro-3-iodopyridine, 98 +%. The chemical properties of this substance are quite stable. Looking at its structure, the existence of the pyridine ring endows it with a certain aromaticity. Although the chlorine and iodine atoms have certain reactivity, they are affected by the electron cloud distribution of the pyridine ring, and the reactivity is restricted.
In common organic solvents, its solubility is good, and it is slightly less soluble in non-polar solvents such as n-hexane, but it can be well dissolved in polar solvents such as dichloromethane, N, N-dimethylformamide, which is convenient for operation.
From the perspective of reaction, chlorine and iodine atoms can participate in nucleophilic substitution reactions. However, due to the electron-absorbing effect of the pyridine ring nitrogen atom, suitable conditions are required for the attack of nucleophiles. If the conditions are improper, the reaction may be difficult to occur, or side reactions may occur, which in turn reflects its chemical stability.
Thermal stability is also worth mentioning. Under conventional heating conditions, 2-chloro-3-iodopyridine is not easy to decompose and can maintain its structure intact. In case of extreme conditions such as strong heat and strong oxidants, the structure may be damaged.
In summary, 2-chloro-3-iodopyridine, 98 +%, is chemically stable under general chemical operating conditions, providing a convenient basis for related research and production. However, special conditions need to be taken into account when using it.

The preparation method of 2-chloro-3-iodopyridine, 98 +%, is a key subject in the field of chemical synthesis. To obtain this compound, several ways are often followed.
First, pyridine can be prepared by halogenation reaction starting from pyridine. First, under suitable reaction conditions, pyridine interacts with chlorination reagents to obtain chlorine-containing pyridine derivatives. During the chlorination process, the reaction temperature, time and reagent dosage need to be carefully controlled. Due to the different activities of hydrogen atoms at different positions on the pyridine ring, it is necessary to precisely replace hydrogen at specific positions with chlorine atoms. Commonly used chlorination reagents include thionyl chloride, phosphorus oxychloride, etc., which are selected according to the different reaction requirements and conditions. After obtaining a chloropyridine-containing derivative, it reacts with an iodizing reagent to introduce iodine atoms. The iodization reaction also requires strict control of conditions to ensure that the iodine atom smoothly replaces the hydrogen at the desired position and avoids the occurrence of side reactions. Commonly used iodizing reagents such as potassium iodide and cuprous iodide should be reasonably selected according to the specific reaction situation.
Second, it can also be prepared by the method of functional group transformation through specific pyridine derivatives as starting materials. If the pyridine ring of the starting material already has a functional group that can be converted into a functional group, and the chlorine atom and the iodine atom can be introduced separately through appropriate reaction steps, this approach is also quite feasible. However, this process requires a deep understanding of the reaction mechanism of functional group transformation, and can precisely control the conditions of each step of the reaction to ensure that each step of the reaction proceeds in the expected direction, so as to improve the yield and purity of the target product.
Third, the reaction involving organometallic reagents is also an effective strategy for the preparation of 2-chloro-3-iodine pyridine. The reaction of organometallic reagents containing pyridine structure with halogenated reagents realizes the introduction of chlorine atoms and iodine atoms at specific positions in the pyridine ring through the unique reaction mechanism of metal-organic chemistry. This method requires strict reaction conditions, and an anhydrous and oxygen-free environment is often necessary, and the preparation and use of organic metal reagents need to be extra careful to ensure the smooth progress of the reaction and the quality of the product.
All these preparation methods have their own advantages and disadvantages. In actual production, it is necessary to comprehensively consider the cost of raw materials, the difficulty of controlling the reaction conditions, the yield and purity of the product, and many other factors, and carefully select the appropriate method to achieve the purpose of efficient preparation of 2-chloro-3-iodopyridine.

2-Chloro-3-iodopyridine, 98 +%. This is a chemical reagent, and its market price often fluctuates due to many factors, making it difficult to generalize.
In the past, in books such as "Tiangong Kaiwu", although there is no record of the price of such specific chemical reagents, it can be explained from the traditional business. Looking at the chemical reagent market today, the abundance of raw materials, the difficulty of preparation, and the amount of demand are all key.
If the raw materials are easily available, the preparation process is not very complicated, and the market demand is stable, the price may be relatively easy. On the contrary, if the raw materials are scarce, the preparation requires exquisite craftsmanship and high cost, and the demand is strong, the price will be high.
For 2-chloro-3-iodopyridine, the introduction of chlorine and iodine may require specific conditions and steps, resulting in different preparation costs. And in the fields of medicine, chemical synthesis, etc., if the demand is strong, the price will also be affected by it.
Usually, the reagent used in small-scale experiments has a higher price per gram due to the small quantity and the cost of preparation, packaging, transportation, etc.; while a large number of purchases are used in industrial production, due to the scale effect, the unit price may be significantly reduced.
Therefore, to know the exact market price, when consulting the reagent supplier or referring to the recent quotation of the chemical product trading platform, the accurate number can be obtained.
