2-Amino-5-iodopyridine is an important compound in organic synthesis. Its synthesis method has been explored by many predecessors, and it is now described in detail.
First, 2-aminopyridine is used as the starting material. First, 2-aminopyridine is reacted with a suitable iodine substitution reagent, such as iodine elemental (I ²), under specific reaction conditions. This reaction requires suitable catalysts, such as copper salt catalysts, and suitable bases, such as potassium carbonate (K 2O CO 🥰). In an organic solvent, such as N, N-dimethylformamide (DMF), heated and stirred, after electrophilic substitution reaction, the iodine atom replaces the hydrogen atom at the 5-position on the pyridine ring, and then obtains 2-amino-5-iodine pyridine.
Second, the pyridine derivative is used as the starting material. First, the pyridine ring is appropriately modified, and a suitable substituent is introduced, and then the amino group and iodine atom are constructed at the desired position through multi-step reaction. For example, a transformable group such as a halogen atom is introduced into the 5-position of the pyridine ring first, and then the nucleophilic substitution reaction is carried out to replace other halogen atoms with an amino group, and then the 5-position substituent is converted into an iodine atom through an iodine substitution reaction, and the final product is obtained.
Third, a nitrogen-containing heterocyclic compound is also used as the starting material to prepare 2-amino-5-iodine through a series of reactions such as cyclization and functional group conversion. This path often requires fine design of the reaction steps to ensure the selectivity and yield of each step.
All methods of synthesis have their own advantages and disadvantages. The choice of starting materials, the control of reaction conditions and the purification of intermediate products all have a significant impact on the yield and purity of the final product. Synthesizers need to follow their own actual conditions, such as raw material availability, experimental equipment, etc., in order to achieve the purpose of efficient synthesis of 2-amino-5-iodopyridine.

2-Amino-5-iodopyridine is an organic compound with interesting physical properties and is closely related to many chemical and pharmaceutical syntheses.
This substance is mostly solid at room temperature, white to light yellow crystalline powder, which is easy to store and use. Its melting point is 155-158 ° C. It is structurally stable within a specific temperature limit, and physical state changes will occur beyond this temperature. The characteristics of the melting point are of great significance for the separation, purification and identification of compounds. Its purity can be judged by melting point measurement.
2-amino-5-iodopyridine is slightly soluble in water, but easily soluble in common organic solvents such as ethanol, dichloromethane, N, N-dimethylformamide (DMF), etc. This solubility is due to its molecular structure. The presence of amino groups and pyridine rings imparts a certain polarity to the molecule, while the introduction of iodine atoms changes the polarity and spatial structure of the molecule as a whole, resulting in different interactions with water and organic solvents. In organic synthesis, suitable solvents can be selected according to this solubility to promote the smooth progress of the reaction, or for the separation and purification of products.
Furthermore, 2-amino-5-iodopyridine has certain sublimation properties. Although the sublimation temperature is quite high, it can be sublimated under reduced pressure and moderate heating conditions. The sublimation characteristics provide a unique way for its purification, especially suitable for preparation scenarios with strict purity requirements.
In addition, its stability cannot be ignored. Under conventional environmental conditions, 2-amino-5-iodopyridine is relatively stable, but it needs to avoid contact with strong oxidants, strong acids, strong bases and other substances. The amino groups, iodine atoms and pyridine rings in its structure can undergo chemical reactions under specific conditions, resulting in structural changes of compounds, which affect their properties and uses.

2-Amino-5-iodopyridine is one of the organic compounds, which is widely used in medicine, pesticides and materials science. Its market price often fluctuates due to a variety of factors.
The first to bear the brunt is the cost of raw materials. If the price of the starting material required for the synthesis of 2-amino-5-iodopyridine rises, the cost of the product will also rise, which will affect the market price. If the supply of raw materials is short, the price will fluctuate, which will also make the price of 2-amino-5-iodopyridine unstable.
Furthermore, the complexity of the production process is closely related to the cost. If the production process is complicated, requiring many steps, special equipment or harsh reaction conditions, it will undoubtedly increase the production cost, thereby raising the market price. And if high catalysts or solvents are required in the production process, the cost will also increase significantly.
The market supply and demand relationship also affects its price. If the market has strong demand for 2-amino-5-iodopyridine and limited supply, the price will rise; conversely, if there is excess supply and low demand, the price will tend to fall. For example, if the demand for it in the pharmaceutical industry surges in a certain period, but the production capacity does not keep up in time, the price will rise.
Regional differences are also factors that cannot be ignored. Different regions have different prices due to production costs, transportation costs, tax policies, etc. If transportation is inconvenient, transportation costs will increase, and product prices will also be higher.
Generally speaking, its market price fluctuates widely, ranging from tens to hundreds of yuan per gram. For the exact price, you need to consult chemical product suppliers in detail, because they can provide accurate quotations according to current market conditions.

2-Amino-5-iodopyridine is an organic compound. When storing and transporting, many things need to be paid attention to to to ensure its stability and safety.
First storage environment. It should be placed in a cool, dry and well-ventilated place. If the ambient humidity is too high, it is easy to cause moisture and deterioration, or cause chemical reactions; if the temperature is too high, it may accelerate its decomposition rate, or even trigger dangerous reactions. Therefore, it is necessary to strictly control the temperature and humidity, usually at a temperature of 5-30 ° C and a relative humidity of 40% -60%.
Times are packaging materials. Well-sealed packaging materials must be used to prevent contact with air, moisture, etc. In general, glass bottles or plastic bottles can be used as storage containers, but for long-term storage, it is recommended to use glass bottles and fill them with inert gas to further isolate the air. During transportation, the packaging should be stable and can resist vibration and collision, so as to avoid material leakage due to package damage.
Furthermore, 2-amino-5-iodopyridine has certain toxicity and irritation. During storage and transportation, it is necessary to avoid direct contact. Operators must wear appropriate protective equipment, such as gloves, protective glasses and protective clothing. In the event of a leak, emergency measures should be taken immediately to evacuate unrelated personnel, isolate the leak area, and properly dispose of the leak in accordance with relevant regulations.
In addition, the storage and transportation of this substance also need to follow regulations and standards. Enterprises should obtain appropriate permits and qualifications and operate in strict accordance with regulations. When transporting, use compliant transportation tools and ensure that transporters are familiar with their characteristics and emergency treatment methods.
In short, the storage and transportation of 2-amino-5-iodopyridine needs to be treated with caution, from the environment, packaging, protection to regulatory compliance, every step cannot be ignored, so as to ensure the safety and stability of the whole process.
