The synthesis method of 3-fluoro-2-iodobenzonitrile has been known for a long time. There are many methods, and each has its own advantages and disadvantages, and it needs to be selected according to the actual situation.
First, take o-fluorobenzoic acid as the starting material, acylation, amination, and then dehydration to obtain o-fluorobenzonitrile. Then, under specific conditions, it interacts with iodine substitutes to obtain 3-fluoro-2-iodobenzonitrile. In this path, during acylation, reagents such as thionyl chloride can be used to convert o-fluorobenzoic acid into acyl chloride at an appropriate temperature and reaction time. When ammoniating, it is necessary to choose a suitable ammonia source and control the reaction conditions to form o-fluorobenzamide. In the dehydration step, a suitable dehydrating agent is selected to promote the dehydration of o-fluorobenzamide to form o-fluorobenzonitrile. Finally, during iodine substitution, according to the characteristics of the iodine substitution reagent, the temperature, reaction time and other factors are regulated to achieve the synthesis of the target product.
Second, 2-iodobenzoic acid is used as the starting material, and 2-iodobenzonitrile is obtained after similar acylation, ammonization and dehydration. Then it is converted into 3-fluoro-2-iodobenzonitrile through fluorination reaction. During fluorination reaction, the choice of fluorine source is crucial, such as choosing a specific fluorine-containing reagent, and reacting in a specific reaction system with At the same time, it is necessary to pay attention to the control of reaction temperature, pressure and other conditions to prevent side reactions from occurring and ensure the purity and yield of the product.
Third, there are also those who use halogenated aromatics as starting materials. First, through the metal catalytic coupling reaction, a cyanyl group is introduced to construct the benzonitrile skeleton. Then, through the halogen atom exchange reaction or direct halogenation reaction, fluorine atoms and iodine atoms are introduced to form 3-fluoro-2-iodobenzonitrile. In the metal catalytic coupling reaction, a suitable metal catalyst, such as palladium, nickel and other catalysts, is selected, and the corresponding ligand is matched to react in a suitable solvent. During the halogen atom exchange or halogenation reaction, the desired synthesis effect is achieved by fine regulation according to the selected reagents and reaction conditions.
Each method of synthesis has its own advantages and disadvantages. In actual operation, it is necessary to consider the availability of raw materials, the level of cost, the difficulty of controlling reaction conditions, and the purity and yield of the product, and make a careful choice to achieve the best synthetic effect.

3-Fluoro-2-iodobenzonitrile is an organic compound. During storage and transportation, many things need to be paid attention to to to ensure safety.
When storing, the first choice of environment. When placed in a cool and ventilated place, away from fire and heat sources. Because of its certain chemical activity, high temperature is easy to react and cause danger. The temperature of the warehouse should be strictly controlled, generally not exceeding 30 ° C, and the relative humidity should also be maintained in an appropriate range to prevent moisture decomposition or deterioration. This compound should be stored separately from oxidants, acids, bases, etc., and must not be mixed. Due to its active chemical properties, contact with these substances may cause severe reactions, such as combustion, explosion and other serious consequences. At the same time, the storage area should be equipped with suitable materials to contain leaks, so that in the event of an accident, measures can be taken quickly to reduce the harm.
During transportation, there are also many key points. The packaging must be tight to ensure that the packaging will not be damaged and leaked during transportation due to vibration, collision, etc. The transportation vehicle must be equipped with the corresponding variety and quantity of fire protection equipment and leakage emergency treatment equipment. During transportation, follow the specified route and do not stop in residential areas and densely populated areas. Because if the compound leaks, it may cause serious harm to personnel and the environment. During transportation, drivers and escorts must strictly abide by the operating procedures, pay close attention to the status of the goods, and take effective measures immediately if any abnormalities are detected.
In short, 3-fluoro-2-iodobenzonitrile needs to pay great attention to the environment, packaging, co-storage and emergency treatment during storage and transportation, so as to ensure the safety and stability of the whole process and avoid accidents.

I look at this question and ask about the market price of 3-fluoro-2-iodobenzonitrile. However, the market price of this chemical is difficult to determine, because it is affected by many factors.
First, the trend of supply and demand is the key. If the demand for this product is strong and the supply is limited, the price will rise; on the contrary, if the supply exceeds the demand, the price will fall.
