The synthesis method of [4- (4-hydroxy-3-iodophenoxy) -3,5-diiodophenyl] acetic acid has been explored by chemists since ancient times and now. There are many methods, each with its own strengths. The following are selected from the main ones, and the ancient Chinese say.
First, halogenated benzene is used as the beginning, and the method of phenylation makes the halogen atom replaced by the hydroxyl group, so that the hydroxyl-containing benzene is obtained. Then, iodine is replaced by iodine, and the iodine atom is introduced at a specific position in the benzene ring to obtain the iodine-containing benzene derivative. Then, by etherification, the hydroxyl-containing benzene is connected to another halogenated benzene to form an ether bond structure. After carboxylation, a carboxyl group is added at a specific position to obtain the target product.
Second, benzene containing phenolic hydroxyl groups is used as the starting material. First, iodine atoms are introduced into the benzene ring with iodine substitution reagent according to specific reaction conditions to obtain intermediates with iodine and phenolic hydroxyl groups. Then, by nucleophilic substitution, phenolic hydroxyl groups are formed with halogenated phenyl ethers to construct ether bonds. Finally, through a specific carboxylation reaction, carboxyl groups are introduced at suitable check points to complete the synthesis of the target product.
Third, phenyl ring compounds with specific substituents are selected, and with the help of organometallic reagents, halogen-metal exchange reactions are carried out to generate active metal-organic intermediates. Then react with iodine-containing electrophilic reagents to introduce iodine atoms. After a series of reactions, including ether bond formation, carboxyl group introduction and other steps, this [4- (4-hydroxy-3-iodophenoxy) -3,5 -diiodophenyl] acetic acid can also be obtained.
The synthesis methods depend on the availability of raw materials, the difficulty of reaction, and the high and low yield. However, fine operation and strict control of the reaction conditions are required to obtain pure products for subsequent research and application.

[4- (4-hydroxy-3-iodophenoxy) -3,5-diiodophenyl] acetic acid. When using this product, many matters must be paid attention to.
First, it is safe, and its nature may be unknown. During operation, protective equipment, such as gloves, goggles, etc., must be worn to prevent contact with skin and eyes, causing injury to the body. If you accidentally touch it, rinse it with plenty of water quickly, and in serious cases, seek medical attention urgently.
Furthermore, it is related to storage. It needs to be placed in a dry, cool and ventilated place, away from fire and heat sources. Because of its sensitivity to heat and light, improper environment, or deterioration, it loses its effectiveness, and even causes dangerous changes.
The use environment is also important. When used in a well-ventilated place, if in a closed place, its volatile substances may cause air pollution and endanger people. And do not approach acids and alkalis and other substances to prevent chemical reactions and cause disasters.
Weighing and dosage also need to be accurate. According to the needs of experiment or production, measure carefully, not more or less. Too much is wasteful, and may cause adverse reactions; too little is not the expected effect.
Operation steps must be followed according to the specifications. Know the relevant process in advance, follow it step by step, and do not change it at will. Every step is related to success or failure and safety. If there is a slight mistake, it is easy to make mistakes.
At the end of the day, after use, properly dispose of the remaining materials and waste. Do not discard at will, and dispose of it according to the prescribed law, so as not to pollute the environment and cause harm to all parties. In this way, the use process will be smooth and safe, and the intended purpose will be achieved.
