Its iodine atom has high reactivity and is easy to participate in nucleophilic substitution reactions. Because the electron cloud density of the benzene ring is affected by iodine and methyl, nucleophilic reagents are more likely to attack specific locations of the benzene ring. Methyl is the power supply group, which will increase the electron cloud density of the benzene ring ortho and para-sites, causing nucleophilic substitution reactions to occur more easily at these locations.

What are the synthetic methods of 5-iodo-2-methybenzoic Acid?
There are several ways to synthesize 5-iodine-2-methylbenzoic acid.
One of them can be obtained from 2-methylbenzoic acid and obtained by iodization reaction. Among them, the choice of iodizing reagents is quite critical. Common ones, such as iodine ($I_ {2} $) combined with an appropriate oxidant. If hydrogen peroxide ($H_ {2} O_ {2} $) is used in combination with it, heat the reaction in a suitable solvent, such as glacial acetic acid. Glacial acetic acid can provide a mild environment for the reaction and promote the reaction. $H_ {2} O_ {2} $As an oxidant, iodine can be oxidized into a more active iodine cation ($I ^{+}$), and then electrophilic substitution reaction with the benzene ring of 2-methylbenzoic acid. The reaction mechanism is roughly as follows: $H_ {2} O_ {2} $and $I_ {2} $Under acidic conditions, $I ^{+}$,$ I ^ {+} $attack the adjacent and para-sites on the benzene ring of 2-methylbenzoic acid. Due to the fact that methyl is an ortho-site group and the steric hindrance and other factors, the iodine atom is mainly substituted in the ortho-site of methyl to generate 5-iodine-2-methylbenzoic acid.
Second, we can also start from 2-methyl-5-nitrobenzoic acid. The nitro group is first reduced to an amino group, and the commonly used reducing agents are iron and hydrochloric acid. After this step, 2-methyl-5-aminobenzoic acid is obtained. Then, through a diazotization reaction, sodium nitrite is treated with hydrochloric acid to form a diazonium salt. Then the diazonium salt is reacted with potassium iodide, and the diazonium group is replaced by an iodine atom to obtain 5-iodine-2-methylbenzoic acid. In this process, the diazotization reaction needs to be carried out at a low temperature to prevent the decomposition of the diazonium salt and ensure the smooth progress of the reaction.
Furthermore, 2-methylbenzoic acid can be obtained by haloform reaction with 2-methylbenzaldehyde as raw material. Then according to the first method mentioned above, iodization is carried out, and 5-iodine-2-methylbenzoic acid can also be obtained. In the haloform reaction, the commonly used reagents are sodium hypochlorite, etc. Under basic conditions, 2-methylbenzaldehyde is converted to 2-methylbenzoic acid, and haloform is generated at the same time. The subsequent iodization reaction, as described above, can achieve the synthesis of the target product by selecting suitable reagents and conditions.
5-iodo-2-methybenzoic the market price of Acid
5-Iodine-2-methylbenzoic acid, the price of this product in the market is difficult to determine. Its price often changes due to many reasons, just like the changing situation, elusive.
First, the source of production is the key reason. If the origin is vast and the output is abundant, the price may become more affordable. However, if the production area is scarce and the output is thin, the price will be high. And the quality of different origins is also different. Those with high purity will not be low; if the purity is poor, the price may be slightly inferior.
Second, the supply and demand of the city will determine the price. If there are many users, the demand will exceed the supply, and the price will rise, just like the state of rising waters. On the contrary, there are few people who need it, and the supply exceeds the demand, and the price will be suppressed, just like water at low tide.
Third, the preparation method also has an impact. If the production method is simple, the cost is controllable, and the price is appropriate. If the preparation is complicated, exquisite skills and expensive raw materials are required, the price will be high.
Fourth, the changing times also affect the price. The passage of time, the rise and fall of the economy, and the change of policies can all make prices fluctuate. If the economy is prosperous, all industries are booming, and demand or increase, the price will move accordingly; policy regulation affects supply and demand, and the price is also controlled by it.
Therefore, in order to know the exact market price of 5-iodine-2-methylbenzoic acid, it is necessary to gather information from all parties, and carefully check the sources of production, supply and demand, production methods, and changes in time to obtain a more accurate number. Do not believe in a single theory. When drawing on various sources, judge them cautiously.
5-iodo-2-methybenzoic Acid during storage and transportation
5-Iodine-2-methylbenzoic acid is an organic compound. During storage and transportation, many matters need to be paid attention to to ensure its quality and safety.
First, when storing, find a cool, dry and well-ventilated place. This compound is easy to decompose when heated, and high temperature environment may cause it to deteriorate, so it should avoid direct sunlight and heat sources. The temperature of the warehouse should be controlled between 15 ° C and 30 ° C, and the humidity should be maintained at 40% to 60%. If the humidity is too high, it may cause the compound to get damp, which will affect its purity; if the humidity is too low, it may cause its volatilization to increase.
Second, be sure to store it separately from oxidants, reducing agents, alkalis and other substances. 5-Iodine-2-methylbenzoic acid has a certain chemical activity, contact with the above substances, or trigger chemical reactions, and even cause fire, explosion and other hazards. For example, oxidizing agents or causing their oxidation, changing the chemical structure and properties.
Third, the storage container should be made of corrosion-resistant materials, such as glass, ceramics or specific plastic materials. Because the compound contains iodine and carboxyl groups, it has a corrosive effect on some metals. If it is stored in a metal container, or a corrosive reaction occurs, it will not only affect the quality of the compound, but also cause damage to the container and cause leakage.
Fourth, during transportation, ensure that the container is well sealed to prevent leakage. Transportation vehicles should be equipped with corresponding fire equipment and leakage emergency treatment equipment. And when transporting, it is necessary to follow the specified route to avoid passing through densely populated areas and water source reserves. If a leak occurs on the way, emergency measures should be taken immediately to evacuate the surrounding people and properly collect and deal with the leak.
In short, when storing and transporting 5-iodine-2-methylbenzoic acid, it is necessary to operate in strict accordance with relevant specifications and requirements, and attach great importance to safety and quality in order to effectively prevent accidents and ensure the safety of personnel and the environment.
