The synthesis method of 3-hydroxy-2-iodine-6-methylpyridine is quite complicated and requires specific chemical principles and steps. There are generally the following synthetic routes.
First, a specific pyridine derivative can be initiated. First, a suitable parent pyridine is selected, and its structure needs to be similar to the target product for subsequent modification. For example, a pyridine compound with a suitable substituent is selected, and under specific reaction conditions, the halogenation reaction is carried out. Iodine atoms are introduced into the pyridine ring at specific positions in a suitable catalyst and solvent environment with an iodine source. This step requires fine control of the reaction temperature, time and the ratio of the reactants to ensure that the iodine atoms fall accurately at position 2. Then, the obtained product is hydroxylated to introduce 3-hydroxyl groups. This hydroxylation step may require the use of specific nucleophiles to achieve the substitution of hydroxyl groups to specific groups under basic or other suitable conditions, and then obtain the key structure of the target product.
Second, the strategy of gradually constructing the pyridine ring can also be adopted. First, a small molecule compound containing nitrogen and carbon is used as the raw material to construct the pyridine ring through a multi-step reaction. For example, with appropriate aldose, ketone and nitrogen-containing compounds, under acidic or basic catalysis, a series of reactions such as condensation and cyclization are formed to form the pyridine ring. In the cyclization process, by rationally designing the structure of the reactant, the methyl group is pre-positioned at the No. 6 position. Then, as in the previous method, iodine atoms and hydroxyl groups are introduced in sequence to complete the synthesis of 3-hydroxy-2-iodine-6-methyl pyridine. Although this approach has many steps, precise control of the reaction conditions can effectively improve the purity and yield of the product.
Furthermore, the method of transition metal catalysis may be used. Using the unique catalytic properties of transition metals, such as palladium, copper and other metal catalysts, coupling reactions between the reactants can occur. Using iodine-containing reagents, hydroxyl-containing reagents and methyl-containing pyridine derivatives as raw materials, in the presence of transition metal catalysts, by adjusting the reaction parameters, each group is connected at the target position on the pyridine ring to achieve the synthesis of 3-hydroxy-2-iodine-6-methyl pyridine. This method often exhibits the advantages of high efficiency and good selectivity, but it requires a lot of catalyst selection and reaction conditions optimization.

3-Hydroxy-2-iodine-6-methylpyridine, this compound is an organic compound. Looking at its structure, the hydroxyl group, iodine atom and methyl group each occupy a specific position in the pyridine ring, and this unique structure endows it with many physical properties.
When it comes to appearance, it is usually white to light yellow crystalline powder, with fine texture and fine crystal luster under light. This is due to the orderly arrangement of molecules and the regular crystal structure.
In terms of solubility, the compound is slightly polar. The presence of hydroxyl groups makes it soluble in polar solvents such as methanol and ethanol. However, the hydrophobicity of the pyridine ring and the methyl group and iodine atoms limits its solubility. The solubility in water is relatively small, because the force between the water molecule and the compound is not enough to overcome the intermolecular force. In organic solvents such as dichloromethane and chloroform, the solubility is relatively good. Due to the principle of similar phase dissolution, the organic solvent can form a moderate interaction with the compound molecule.
Melting point is also an important physical property. The melting point is experimentally determined to be in a specific temperature range. This is determined by the intermolecular force. Interactions such as hydrogen bonds and van der Waals forces between molecules make the molecules arranged in an orderly manner. When heating up, sufficient energy is required to overcome these forces in order to cause crystal melting. The specific melting point reflects the strength and stability of the intermolecular force.
In addition, the compound has a certain degree of volatility. Although the degree of volatility is not high, under a specific temperature and environment, the molecules can escape from the solid surface and enter the gas phase. This is related to its molecular energy and intermolecular forces. Molecules with higher energy can easily overcome the binding and enter the gas phase.

3-Hydroxy-2-iodine-6-methylpyridine, this is an organic compound. It has the following chemical properties:
- ** acidic-basic **: Due to the presence of hydroxyl groups, the compound can be acidic under certain conditions. The hydrogen atom of the hydroxyl group can be partially dissociated, showing acidic properties. However, its acidic strength is affected by the pyridine ring and other substituents. The nitrogen atom of the pyridine ring has a certain electronegativity, which can change the density of the hydroxyl electron cloud, which in turn affects the difficulty of dissociation of the hydrogen atom.
- ** Nucleophilic Substitution Reaction **: The iodine atom in the molecule is active and susceptible to attack by nucleophilic reagents, resulting in nucleophilic substitution Nucleophiles can provide electron pairs to interact with iodine atoms, causing iodine ions to leave and form new compounds. For example, by reacting with nucleophiles such as sodium alcohol, ether compounds can be formed; by reacting with amine nucleophiles, nitrogen-containing new compounds can be obtained.
- ** Redox properties **: Hydroxyl groups can be oxidized. Moderate oxidizing agents can oxidize them to carbonyl groups to form corresponding pyridinone compounds. Conversely, if there are suitable reducing agents in the system, the substituents on the pyridine ring or the pyridine ring itself may undergo a reduction reaction, but specific reaction conditions and suitable reducing agents are required. < Br > - ** Coordination Properties **: The nitrogen atom of the pyridine ring has a lone pair of electrons, which can be used as a ligand to form a coordination compound with metal ions. This coordination effect may affect the physical and chemical properties of the compound, and also has potential applications in catalysis, materials science and other fields.
- ** Aroma-related Reactions **: The pyridine ring is aromatic and can undergo reactions such as electrophilic substitution. Although the reaction activity is slightly different from that of the benzene ring due to the electronegativity of the nitrogen atom, substituents can still be introduced at specific positions on the pyridine ring under appropriate conditions.

The price range of 3-hydroxy-2-iodine-6-methylpyridine in the market is difficult to determine. This is due to the changeable market conditions, and its price often changes for various reasons.
If you look at the past, the price of chemical materials in the past was mostly affected by the dependence of supply and demand, the price of raw materials, the simplicity of manufacturing, and the regulation of political regulations. This 3-hydroxy-2-iodine-6-methylpyridine, if the raw materials are easily available and the supply exceeds the demand, the process is also simple, and the price is slightly cheaper; on the contrary, if the raw materials are rare, the process is complicated, and there are many people who want it, the price will be high.
However, today is different from the past, the city is unpredictable, and it is difficult to measure it. Or when it comes to chemical cities, ask merchants and inspect quotations, or you can know the approximate price. However, even if the price is obtained at that time, it may change a little, because of the constant dynamics of the city, it is difficult to determine the price for a long time. Therefore, if you want to know its accurate price, it is essential to inquire and scrutinize the market situation in real time.
