2-Chloro-3-iodine-5- (trifluoromethyl) pyridine, this is an organic compound with unique physical properties. It is mostly solid at room temperature due to intermolecular forces. The melting point is about [X] ° C, and this value varies slightly due to the purity of the substance.
Looking at its appearance, it is often white to light yellow crystalline powder. This color is derived from the absorption and reflection characteristics of the molecular structure to light. Its solubility also has characteristics. It has good solubility in organic solvents such as dichloromethane and chloroform. Due to the principle of similar miscibility, these organic solvents can form appropriate forces with the molecules of the compound. However, it has little solubility in water. Due to the large difference between molecular polarity and water, it is difficult for water to overcome the intermolecular forces of the compound to disperse it.
The density of this compound is about [X] g/cm ³, and the density value depends on the molecular weight and the degree of molecular accumulation. And it has a certain stability and is not easy to decompose under normal conditions. However, in case of strong oxidizing or reducing agents, due to the activity of its own halogen atom and trifluoromethyl, or a chemical reaction occurs.
In addition, its vapor pressure is low, indicating that it has a small tendency to volatilize to the gas phase at room temperature. This property has a great impact on the safety of storage and use. Under conventional storage conditions, the volatilization loss is small, and its chemical composition and properties can be maintained stable.

2-Chloro-3-iodine-5- (trifluoromethyl) pyridine is a kind of organic compound. Its chemical properties are unique and have many commonalities of halogenated pyridine compounds.
In terms of its activity, due to the presence of chlorine, iodine and trifluoromethyl in the molecule, its chemical activity is quite high. Chlorine and iodine, as halogen atoms, can participate in nucleophilic substitution reactions. Under suitable conditions, nucleophiles can attack carbon atoms connected to halogen atoms, and the halogen atoms leave, thereby realizing the conversion of functional groups. For example, when reacted with nucleophiles such as alkoxides and amines, corresponding ethers or amine derivatives can be formed. The introduction of
trifluoromethyl has a significant impact on the properties of the compound. This group has strong electron-absorbing properties, which can reduce the electron cloud density of the pyridine ring, thereby enhancing the activity of the halogen atoms on the pyridine ring, making nucleophilic substitution reactions more likely to occur. And the presence of trifluoromethyl can also significantly change the physical properties of the molecule, such as increasing the lipid solubility of the compound and affecting its solubility in different solvents.
Furthermore, the pyridine ring in this compound is aromatic and can undergo typical reactions of aromatic compounds, such as electrophilic substitution reactions. However, due to the electron-withdrawing action of trifluoromethyl, the positional selectivity of the electrophilic substitution reaction will be affected, and the reaction check point is more inclined to the relatively high electron cloud density on the pyridine ring.
In addition, the compound may also exhibit specific properties in redox reactions. Halogen atoms can change their oxidation states under the action of suitable oxidizing or reducing agents, and then participate in various organic synthesis and transformation processes, providing the possibility for the construction of more complex organic molecular structures. In short, the chemical properties of 2-chloro-3-iodine-5- (trifluoromethyl) pyridine are rich and diverse, and have important application potential in the field of organic synthetic chemistry.

The determination of the price of 2-chloro-3-iodine-5- (trifluoromethyl) pyridine on the market has not been heard. However, if you want to determine the range of its price, you can think of it from several ends.
First, such pyridine derivatives contain special groups such as chlorine, iodine, and trifluoromethyl. The synthesis process is more than one step. The procurement of raw materials, the control of the reaction, and the purification process all need to be refined. The halogenation reaction of chlorine and iodine requires specific conditions or harsh conditions, and the reagents used also have specific requirements; the introduction of trifluoromethyl often requires special reagents and technologies, such as fluorine-containing reagents, which are quite expensive and cause the synthesis cost to rise. < Br >
Second, the use of this compound is also the key to the price. If it is used in high-end pharmaceutical research and development, as an intermediary of active pharmaceutical ingredients, its price will be high due to strict purity and quality requirements in the pharmaceutical field and high research and development costs; if it is used in pesticide creation, it is a new type of pesticide active ingredient. Considering the size and competition of the pesticide market, the price may be different. And if it is used in the field of materials science, such as the preparation of polymer materials with special properties, the price varies according to the material performance requirements and application scenarios.
Third, the supply and demand of the market also affects its price. If there is a large increase in demand for this product by pharmaceutical companies and scientific research institutions at a certain time, but the supply is limited, if there are few manufacturers and low production capacity, the price will rise; on the contrary, if the supply exceeds the demand, the price will decline.
In summary, it is difficult to determine the exact price without exact market conditions. However, based on its synthesis difficulty and special groups, the price per gram may be between hundreds and thousands of yuan. But this is only speculation, and the actual price needs to be consulted with chemical raw material suppliers and chemical trading platforms to obtain real-time and accurate prices.
