4-Amino-3-iodobenzoic acid is 4-amino-3-iodobenzoic acid. The physical properties of this substance are particularly important, which is related to its application in many fields.
Its appearance is often in a solid form, mostly white to light yellow powdery substance, which is easy to store and transport, and is easy to operate in subsequent processing. Its melting point is of great significance for determining the purity of the substance and the phase transition under specific conditions. It has been experimentally determined that the melting point of 4-amino-3-iodobenzoic acid is within a certain range, which can be used as an important indicator to distinguish the purity. If the impurity content is high, the melting point may be offset.
Furthermore, its solubility is also a key physical property. In common organic solvents, its solubility characteristics vary. In some polar organic solvents, such as methanol, ethanol, etc., there is a certain solubility, while in non-polar solvents, the solubility is relatively small. This difference in solubility is crucial in the process of chemical synthesis, separation and purification, and a suitable solvent can be selected for reaction or separation operations according to this characteristic.
The density of 4-amino-3-iodobenzoic acid is also worthy of attention. Although its value is not widely known, density data is indispensable in precise chemical calculation, such as the ratio of reactants and the accurate preparation of solution concentration. It is related to the reaction process and product quality.
In addition, its stability is also an important physical property. Under specific conditions such as normal temperature and pressure and isolation from air and moisture, the substance is relatively stable. However, if it is exposed to high temperature, high humidity or strong light, it may undergo chemical changes, which will affect its quality and performance. Therefore, during storage and use, it is necessary to fully consider its stability and take appropriate measures to ensure that its properties remain unchanged.

4-Amino-3-iodobenzoic acid has been synthesized in ancient times, and there are many ways. One method is to use benzoic acid as the starting material, and after a delicate reaction sequence, this compound can be formed.
First, benzoic acid is used as the base to perform the technique of nitrification. This step requires careful selection of reagents and conditions, and under appropriate solvents and temperatures, the nitro group can be precisely entered into the specific position of the benzene ring. The proper nitro insertion will pave the way for the subsequent reaction. Usually, mixed acid (a mixture of sulfuric acid and nitric acid) is used as the nitrification reagent, and the temperature control is moderate to avoid side reactions.
After nitrobenzoic acid is obtained, the nitro group is reduced to an amino group by the method of reduction. The combination of traditional multi-purpose iron powder and hydrochloric acid, under mild conditions, the nitro group is converted into an amino group through a series of electron transfer, and then 4-aminobenzoic acid is obtained.
Then, 4-aminobenzoic acid is iodized. During iodization, iodine elements often cooperate with appropriate oxidants, such as hydrogen peroxide. The function of the oxidant is to activate the element of iodine, which makes it easy to have electrophilic substitution with the benzene ring. The iodine atom falls precisely in the amino ortho position, and finally 4-amino-3-iodobenzoic acid is obtained.
Another method is to use aniline as the starting material. Aniline is first acylated to protect its amino group, so as to prevent it from being overactive and causing frequent side reactions in subsequent reactions. The acylated product is then nitrified, and the nitro group enters a specific position according to the positioning rules. After that, the acylation group is removed, and then the target product can be obtained through a series of reactions such as diazotization and iodization. The diazotization reaction requires precise temperature control and reagent ratio, and the iodization step also needs to be carefully operated to obtain pure 4-amino-3-iodobenzoic acid.
The synthesis method has its advantages and disadvantages. It is selected according to many factors such as the availability of raw materials, cost, yield and purity requirements. Although there are various methods of synthesis, it is all due to the ingenuity and exquisite skills of chemists that this compound can be seen in the world and used in many fields.

4-Amino-3-iodobenzoic acid is a chemical substance. When storing and transporting, many matters must be paid attention to.
First, storage. First, it must be placed in a cool, dry and well-ventilated place. This is because if the substance is in a humid and warm environment, or causes changes in its properties, it will affect its quality. Like an ancient collection of books, it must be hidden in a dry place to prevent beetles and mildew. The same is true for this chemical. Second, it should be stored separately from oxidizing agents, acids, alkalis, etc., and must not be mixed. Just like a gentleman does not mix with a villain, chemicals of different natures are mixed, which may cause violent reactions and cause safety risks. Third, the storage place should be equipped with suitable materials to contain the leakage. In case of sudden leakage, it can be collected in time to prevent its spread from causing greater harm.
Subsequent transportation. When transporting, the packaging must be tight and firm. Appropriate packaging materials should be used in accordance with the specifications of chemical transportation to ensure that it will not be damaged and leaked during the bumpy journey. Furthermore, the transportation process should be kept away from fire and heat sources. Fire and heat, for chemicals, such as ignition, can easily trigger dangerous reactions. Transportation vehicles also need to be equipped with corresponding varieties and quantities of fire-fighting equipment and leakage emergency treatment equipment for emergencies. And during transportation, drivers and escorts must be familiar with the nature of the chemical and emergency treatment methods, such as the ancient generals who are familiar with the art of war, in order to deal with emergencies and ensure the safety of transportation.

4-Amino-3-iodobenzoic acid, an organic compound, has important uses in many fields such as medicine and chemical industry. However, its market price range is difficult to determine with certainty, because it is determined by many factors.
The first to bear the brunt is the cost of raw materials. The price fluctuations of the raw materials required for the preparation of 4-amino-3-iodobenzoic acid have a great impact on the price of finished products. If the supply of raw materials is tight, or the cost is high due to the complicated production process, the price of 4-amino-3-iodobenzoic acid will rise.
Furthermore, the difficulty of the production process is also the key. If delicate and complex reaction steps, harsh reaction conditions, or special catalysts and equipment are required, the cost of the production process will be greatly increased, which will push up the price of the product.
The market supply and demand relationship also affects its price. If the market has strong demand for 4-amino-3-iodobenzoic acid, but the supply is relatively scarce, the price will rise; conversely, if the supply exceeds the demand, the price will be under pressure to fall.
In addition, different manufacturers set different prices due to differences in technical level, economies of scale, and operating costs. Large-scale manufacturers may be able to sell products at lower prices due to economies of scale; while small manufacturers may be able to sell products at higher prices due to higher costs.
According to past market conditions and relevant information, the price may range from tens to hundreds of yuan per gram. However, this is only a rough estimate, and the actual price will fluctuate frequently with the changes of the above factors. If you want to get an accurate price, you need to consult the relevant manufacturers, distributors, or refer to recent market transaction data.
