Overall, 3-hydroxy-4-iodobenzyl alcohol is of great value in many fields, promoting the continuous development and progress of various industries.

To prepare 3-hydroxy-4-iodobenzyl Alcohol, the following ancient method can be used.
First take the appropriate starting materials, such as 4-iodobenzoic acid as the starting point, and the target product can be obtained after several steps of conversion. First, 4-iodobenzoic acid is reacted carefully at low temperature in an inert organic solvent such as anhydrous ether with an appropriate reducing agent, such as lithium aluminum hydride (LiAlH). In this step, lithium aluminum hydride has strong reductivity, and the carboxyl group (-COOH) can be reduced to hydroxymethyl (-CH ² OH) to obtain 4-iodobenzyl alcohol.
When reacting, pay attention to the anhydrous and oxygen-free environment of the system to prevent lithium aluminum hydride from decomposing in water and causing the reaction to fail. And the reaction temperature should be controlled at a low temperature, such as about 0 ° C, and then slowly raised to room temperature to make the reaction proceed smoothly. After the reaction is completed, the excess aluminum lithium hydride is carefully quenched with an appropriate amount of water, and then the product is extracted with an organic solvent, and purified by anhydrous sodium sulfate drying, filtration, vacuum distillation, etc., to obtain pure 4-iodobenzyl alcohol.
Then, 4-iodobenzyl alcohol is placed in a suitable reaction vessel, and the mixed acid of concentrated nitric acid and concentrated sulfuric acid is used as a nitrifying agent. Under low temperature conditions, such as 0-5 ° C, the mixed acid is slowly added dropwise to make the benzene ring nitrify. This step requires strict temperature control. Due to high temperature, it is easy to form polynitro substitution by-products. After the reaction is completed, after separation and purification, 3-nitro-4-iodobenzyl alcohol can be obtained.
Then with a suitable reducing agent, such as iron and hydrochloric acid, or palladium carbon hydrogenation, the nitro group is reduced to an amino group to obtain 3-amino-4-iodobenzyl alcohol. This step of reduction reaction conditions need to be suitable. For example, when hydrogenation with palladium carbon, the hydrogen pressure and reaction temperature need to be controlled to ensure a smooth reaction.
Finally, 3-amino-4-iodobenzyl alcohol is reacted by diazotization with sodium nitrite and hydrochloric acid at low temperature (0-5 ° C) to form a diazonium salt, and then heated with water as a solvent to replace the diazonium group with a hydroxyl group to obtain 3-hydroxy-4-iodobenzyl Alcohol. The whole process requires fine operation and proper control of the reaction conditions at each step to obtain the target product with the ideal yield.

I have heard your inquiry about the market price of 3-hydroxy-4-iodobenzyl Alcohol. However, the price of this product often changes due to various reasons, and it is difficult to generalize.
The change in its price is primarily due to the trend of supply and demand. If there are many people who want it, and the supply is small, the price will increase; on the contrary, if the supply exceeds the demand, the price may drop. And the difficulty of its production also affects its price. If the preparation method is complicated, the raw materials are rare, or the cost will rise, the price will also increase.
Furthermore, regional differences also have an impact. In different places, due to differences in taxes, freight and markets, prices may vary. In places where trade is prosperous and logistics is convenient, the price may be slightly lower; while in remote places, due to the difficulty of transportation, the cost increases, and the price may be higher.
In addition, the quality is also the key to the price. Those with high purity and few impurities will be priced higher than those with inferior quality. And the reputation of the brand and the business strategy of the merchant can make the price different. Well-known brands are based on reputation and quality, and the price may be high; while new entrants may be market expansion, and the price may be close to the people.
To know the exact price, you should consult the distributors and traders of chemical raw materials, or explore the trading platforms of chemical products, in order to obtain the current actual price, and you need to carefully check the quality, quantity and other conditions to understand the true meaning of the price.
