The synthesis of 4-hydroxy-3-iodobenzoic acid has different paths. This imitation of "Tiangong Kaiwu" is described in ancient terms.
First, 4-hydroxy benzoic acid can be started. First, 4-hydroxy benzoic acid is met with an appropriate amount of iodizing reagent. This iodizing reagent, such as iodine elemental substance, is compatible with an appropriate oxidizing agent. The oxidizing agent, such as hydrogen peroxide, is in a suitable solvent, such as glacial acetic acid, etc., and is controlled at an appropriate temperature and heated slowly. The control of temperature is about success or failure and cannot be careless, about tens of degrees Celsius. In this environment, the iodizing reagent interacts with 4-hydroxybenzoic acid, and the iodine atom gradually enters the benzene ring and falls at position 3, thus forming 4-hydroxy-3-iodobenzoic acid. After the reaction is completed, the pure product can be obtained by ordinary separation and purification methods, such as recrystallization.
Second, 3-iodine-4-methoxybenzoic acid can also be used as the starting material. First, 3-iodine-4-methoxybenzoic acid is placed in a suitable reaction vessel and heated with a strong acid, such as hydroiodic acid. The power of strong acid can break the connection between the methoxy group and the benzene ring, so that the methoxylation is iodomethane to escape, while the hydroxyl group is left in the benzene ring, so it becomes 4-hydroxy-3-iodobenzoic acid. Thereafter, the impurities are removed by recrystallization and other methods to obtain the refined product.
In addition, it can also be formed by the corresponding halogenated aromatic hydrocarbon through multi-step reaction. First, a suitable halogenated aromatic hydrocarbon is used to interact with the phenolic salt of the alkali metal to introduce a hydroxyl group, and then the iodization step is carried out, which is similar to the previous method. After iodization, separation and purification, 4-hydroxy-3-iodobenzoic acid is finally obtained.
All these synthesis methods have their own strengths and weaknesses, depending on the availability of raw materials, the amount of cost, and the difficulty of reaction.

The market price of 4-hydroxy-3-iodobenzoic acid is difficult to determine. Its price often varies due to many factors, such as the abundance of supply, the difficulty of preparation, the amount of market demand, the quality of the process, and even the current situation. It is all related to the management of merchants.
If the supply is wide and easy to prepare, the process is exquisite and the cost is low, and the market needs to be flat, its price is low; however, if the supply is thin, the preparation is complex and the process is clumsy, the cost is high, and the market needs to be prosperous, the price will be high.
Looking at the chemical raw material market in the past, the prices of various materials fluctuated. In the event of turbulence, logistics obstruction, or sudden changes in supply and demand, the price will also change sharply. Although there is no exact past market for 4-hydroxy-3-iodobenzoic acid, it is deduced from the general practice of chemical substances that its price should be in such variables. Or at some point, due to a breakthrough in preparation, the supply of goods increases and the price drops; or due to the scarcity of raw materials, the preparation is difficult, and the price soars.
To know the exact market price, you need to ask merchants specializing in chemical materials, brokers entering and leaving the chemical market, or scrutinize the real-time market of chemical trading platforms to get a near-real price.

4-Hydroxy-3-iodobenzoic acid is a chemical substance, and more attention should be paid when storing and transporting it.
The first word of storage, because of its nature, should be found in a cool, dry and well ventilated place. If it is in a humid place, it is easy to be damp and deteriorate, causing its chemical properties to become easy, affecting future use. And it is advisable to keep away from fire and heat sources, because the substance may be flammable, in case of open flame or hot topic, it is dangerous to cause fire.
Furthermore, it should be stored separately from oxidizing agents, reducing agents, alkalis, etc. Contact with them, or cause violent chemical reactions, causing danger. In the storage area, suitable materials should be prepared to contain leaks in case of leakage, which can be dealt with in time to prevent their spread and cause greater harm.
As for transportation, it is necessary to ensure that the packaging is complete and the loading is secure. During transportation, the driving should be stable to avoid bumps and vibrations, and prevent material leakage caused by package damage. Transportation vehicles should also be equipped with corresponding fire equipment and leakage emergency treatment equipment. If there is a leak on the way, it can be dealt with immediately. During transportation, follow the prescribed route and do not stop near densely populated areas and important places to prevent leakage from causing serious impact on the people and the environment. Escort personnel must also be familiar with the characteristics of the substance and emergency response methods, and carefully guard the whole process to ensure the safety of transportation.
