The synthesis of 2-hydroxy-5-iodobenzonitrile has been investigated by chemists throughout the ages. One method is to take 2-hydroxy benzonitrile as the initial material, add an appropriate amount of iodine source in a suitable reaction vessel, such as iodine elemental substance ($I_ {2} $), and introduce a suitable catalyst, such as potassium iodide ($KI $) and sulfuric acid ($H_ {2} SO_ {4} $). The temperature control is in a specific range, such as 50-70 ° C. This temperature can not only promote the steady progress of the reaction, but also avoid the disturbance of side reactions. After several hours of reaction, using common separation methods, such as column chromatography, pure 2-hydroxy-5-iodobenzonitrile can be obtained.
There are also 2-methoxy-5-iodobenzoic acid as the starting material. First, the methoxy group is removed and converted to the hydroxyl group with a suitable reagent, such as hydroiodic acid ($HI $). The reaction needs to be heated under the condition of about 80-100 ° C before it can be smooth. After the hydroxyl group is formed, it is dehydrated and nitrified. In dehydration, thionyl chloride ($SOCl_ {2} $) can be selected, and then reacted with cyanide reagents, such as potassium cyanide ($KCN $), at a mild temperature, such as 30-50 ° C. After these several steps, 2-hydroxy-5-iodobenzonitrile can also be obtained.
Furthermore, with 5-iodo2-nitrobenzoic acid as raw material, the first method is reduction, such as iron powder and hydrochloric acid as reducing agent, the nitro group is converted into amino group, and the temperature is about 60-80 ° C. After obtaining 5-iodo-2-aminobenzoic acid, it is reacted with diazotization, treated with sodium nitrite ($NaNO_ {2} $) and hydrochloric acid, at a low temperature, under 0-5 ℃, to form a diazonium salt. After hydrolysis of the diazonium salt, 2-hydroxy-5-iodobenzoic acid can be obtained. Finally, the nitrile reaction can obtain the target product 2-hydroxy-5-iodobenzonitrile. These methods have their own advantages and disadvantages, and chemists should use them according to their actual needs.

2-Hydroxy-5-iodobenzonitrile, an organic compound, requires careful attention during storage and transportation.
Bear the brunt, the storage environment must be dry and cool. Because of its susceptibility to moisture and deterioration, humid environment or chemical reaction, damage quality. Therefore, it should be stored in a dry and ventilated place, away from water sources and moisture.
In addition, temperature control is also crucial. High temperature may disturb the stability of the compound, or even cause decomposition. Generally speaking, it should be stored in a low temperature environment, generally not exceeding 30 ° C.
Storage in the dark should not be ignored. The substance may be sensitive to light, and the reaction process may be accelerated under light, resulting in deterioration of quality. Storage containers should be made of dark or shading materials and placed in a dark place.
When transporting, the packaging must be stable and well sealed. To prevent the package from being damaged due to bumps and collisions during transportation and the compound from leaking. The packaging materials used must be able to resist the chemical attack of the compound.
At the same time, the relevant transportation regulations and regulations should be strictly followed. Because it may belong to the category of hazardous chemicals, the transportation requirements should be clearly defined before transportation, and necessary safety measures and emergency treatment plans should be equipped.
In addition, storage and transportation places should be kept away from fire sources, heat sources and strong oxidants. Because of exposure to open flames, hot topics or contact with strong oxidants, or the risk of combustion and explosion.
In summary, for the storage and transportation of 2-hydroxy-5-iodobenzonitrile, it is necessary to consider its chemical properties in an all-round way, be careful, and ensure that the operation is standardized to ensure the safety of personnel and the quality of the compound.

2-Hydroxy-5-iodine-benzonitrile. The impact of this substance on the environment and the human body is particularly important and should be investigated in detail.
At the environmental end, it may be potentially harmful. If released in nature, or migrated through water flow and soil. The characteristics of iodine and cyanyl in its chemical structure can cause different effects. Iodine may affect the chemical properties of soil and water, change the mineral balance in it, or cause physiological disorders and interfere with its normal growth and reproduction. Cyanide is very toxic, can poison microorganisms, disrupt the balance of soil ecosystems, and affect material circulation and energy conversion. And it degrades slowly in the environment, or remains for a long time, accumulates in the living body, accumulates through the food chain, and poses a greater threat to high-level organisms.
As for the human body, the harm of 2-hydroxy-5-iodine-benzonitrile should not be underestimated. Entering the human body through respiratory tract, skin contact or accidental ingestion can damage multiple systems. It may irritate the respiratory mucosa, cause cough, asthma and other diseases, and even cause respiratory inflammation. Contact with the skin may cause allergies, burns, and damage the skin barrier. If it enters the digestive system, it can corrode the gastrointestinal mucosa, interfere with digestive function, and cause nausea, vomiting, and abdominal pain. In particularly serious cases, cyanyl can inhibit the activity of cellular respiratory enzymes, hinder cellular respiration, cause hypoxia in tissues and organs, damage the nervous system, cardiovascular system, etc., and endanger life and health.
Therefore, in the production, use and disposal of 2-hydroxy-5-iodine-benzonitrile, we should exercise caution and implement strict management and prevention and control measures to reduce its harm to the environment and human body, and ensure ecological and public well-being.
