2-amino-3-bromo-5-iodopyridine

2-Amino-3-bromo-5-iodopyridine is also an organic compound. It has a variety of chemical properties and is quite important.
First of all, its alkalinity. Because its molecule contains an amino group, the nitrogen atom in the amino group has lone pair electrons and can bind protons, so it is alkaline. In acidic media, amino groups are easy to combine with protons to form positively charged ions. This property allows them to participate in many acid-base related reactions.
Describe its nucleophilic substitution reaction. Bromine and iodine atoms on the pyridine ring are both good leaving groups. When encountering nucleophiles, bromine or iodine atoms can be replaced by nucleophiles. Nucleophilic reagents such as alkoxides, amines, etc., can attack the carbon atoms connected to bromine or iodine on the pyridine ring, undergo nucleophilic substitution, and form new compounds. This reaction provides an important way to construct new pyridine derivatives.
Re-discussion of its halogenation reaction. Although the molecule already contains bromine and iodine atoms, it can still be further halogenated under specific conditions. If suitable halogenating reagents and reaction conditions are selected, new halogen atoms may be introduced at other locations on the pyridine ring to enrich the types of halogenated derivatives.
In addition, its reduction reaction is also worthy of attention. The pyridine ring can be reduced under the action of appropriate reducing agents, such as the use of metal hydrides and other reducing agents, the unsaturated structure of the pyridine ring can be partially or completely reduced, thereby changing the electron cloud distribution and spatial structure of the molecule, and derived products with different properties and uses.
2-amino-3-bromo-5-iodine pyridine has a variety of chemical properties due to its own structural characteristics, and has a wide range of application prospects in the field of organic synthesis. Organic compounds with diverse structures can be constructed through different reaction paths.

To prepare 2-amino-3-bromo-5-iodopyridine, there are many methods, and it is as common as Chen's number.
First, pyridine can be used. Under appropriate conditions, pyridine can be halogenated with a specific halogenating reagent to introduce bromine and iodine atoms. If liquid bromine and a suitable catalyst are used, a specific position of pyridine can be brominated, and then an iodine agent can be used to introduce an iodine atom at another position. Then, through nitration reaction, nitro is introduced at a suitable check point, and then the nitro is converted into an amino group by reduction, so that the target product can be obtained.
Second, a compound containing a pyridine ring is used as the starting material. If there are some required substituents, only specific positions need to be modified. For example, a pyridine derivative with bromine atoms can be used to introduce iodine atoms through suitable iodine substitution reagents, and then amino groups can be introduced at appropriate positions through specific amination means to obtain 2-amino-3-bromo-5-iodopyridine.
Third, a pyridine ring can be constructed through a multi-step cyclization reaction and a substituent can be introduced. Using chain compounds containing nitrogen, bromine, and iodine as raw materials, under suitable reaction conditions, through cyclization and condensation, the pyridine ring structure can be formed, and amino groups can be introduced at the same time or subsequently, and the final target product can be obtained. < Br >
Each method has its own advantages and disadvantages, and it needs to be selected according to factors such as the availability of raw materials, the ease of control of reaction conditions, and the yield and purity of the product.

2-Amino-3-bromo-5-iodopyridine is an organic compound. During storage and transportation, many key matters 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, away from fire, heat and strong oxidizing agents. This compound is quite sensitive to light and heat, and light and high temperature can cause it to decompose or deteriorate. Therefore, it should be stored in a container protected from light, and the temperature should be controlled within an appropriate range. Generally, it is better to refrigerate at 2-8 ° C. If long-term storage is required, freezing conditions may be more suitable.
Furthermore, the packaging must be tight. Choose packaging materials that can effectively prevent moisture and oxidation, such as glass bottles with sealing caps, or plastic containers with special barrier properties. If the packaging is damaged, external moisture and oxygen can easily invade, causing chemical reactions, resulting in damage to product quality.
The transportation process should not be underestimated. Relevant regulations and standards should be followed, and proper protective measures should be taken. When handling, it should be handled with care to avoid violent vibration and collision to prevent packaging damage. Transportation tools should be kept clean, dry, and free of other substances that may react with them. At the same time, according to the transportation distance and environmental conditions, it is necessary to reasonably choose the transportation method and temperature control means. For example, long-distance transportation or high temperature environment, cold chain transportation can be considered.
In addition, for the storage and transportation of this compound, relevant personnel should receive professional training, be familiar with its characteristics and latent risks, and master emergency treatment methods. In the event of an unexpected situation such as leakage, correct measures can be taken quickly to reduce the harm.
In short, the storage and transportation of 2-amino-3-bromo-5-iodopyridine requires careful consideration of the environment, packaging, operation and personnel to ensure its quality and safety.

2-Amino-3-bromo-5-iodopyridine, a key organic synthesis intermediate in the field of fine chemicals, is widely used in medicine, pesticides and material science. Its market price fluctuates due to a variety of factors, making it difficult to generalize.
First of all, the purity of high-purity products with a purity of more than 98% can reach hundreds of yuan per gram. Due to the complicated preparation process of high-purity products, high-end separation and purification technology is required, and the cost is quite high. And the purity is slightly lower, such as 90% - 95%, the price per gram may drop to tens of yuan, but it still varies according to the specific purity situation.
Furthermore, in large-scale production, due to the scale effect, the unit cost is reduced, and the price will be more affordable. If it is prepared in small quantities in a laboratory, the price will be relatively high. For example, large chemical enterprises mass produce, and the price per gram may be controlled within 100 yuan; small laboratories customize, and the price per gram may exceed several hundred yuan.
Market supply and demand also affect prices. When demand is strong and supply is short, prices will inevitably rise; if the market supply is sufficient and competition is fierce, prices will decline.
In summary, the market price of 2-amino-3-bromo-5-iodopyridine fluctuates roughly between tens of yuan and hundreds of yuan per gram. The specific price needs to consider factors such as purity, production scale and market supply and demand. When purchasing, be sure to carefully check the product quality and price to meet your own needs and cost budget.
