The synthesis methods of 4-bromo-1-iodine-2-trifluoromethyl-benzene are quite diverse. The common method is to use benzene derivatives containing trifluoromethyl as the starting material and undergo halogenation reaction.
First, 2- (trifluoromethyl) aniline can be used as the starting material. First, it is diazotized with sodium nitrite and hydrobromic acid to form a diazonium salt. Subsequently, potassium iodide is added, and the diazo group is replaced by iodine to obtain 1-iodine-2- (trifluoromethyl) benzene. This product is then brominated with bromine in the presence of suitable catalysts such as iron powder or iron tribromide. Due to the localization effect of substituents on the benzene ring, bromine atoms will be mainly substituted at specific positions to produce 4-bromo-1-iodine-2- (trifluoromethyl) benzene.
Second, 2- (trifluoromethyl) benzoic acid is used as the starting material. It is first converted into the corresponding acid chloride, and then reduced to give 2- (trifluoromethyl) benzaldehyde. Then, through haloform reaction, halogen atoms can be introduced. For example, with sodium hypobromite, bromine atoms can be introduced at specific positions in the benzene ring. Subsequent to a suitable iodization reaction, the target product can be synthesized.
Alternatively, 1-bromo-2- (trifluoromethyl) benzene is used as a raw material. By selecting a specific iodizing agent, such as iodine elemental substance and suitable oxidizing agent, under appropriate reaction conditions, such as the presence of suitable solvents, temperatures and catalysts, iodine atoms can be introduced into the benzene ring to obtain 4-bromo-1-iodine-2- (trifluoromethyl) benzene. These methods have their own advantages and disadvantages, and should be selected according to actual needs and conditions.

4-Bromo-1-iodine-2 - (trifluoromethyl) benzene must be paid attention to during storage and transportation.
This substance has certain chemical activity. When stored, the first environment is dry. Because of its exposure to water or water vapor, or chemical reactions such as hydrolysis, the quality is damaged. The humidity of the warehouse should be controlled at a low level, such as relative humidity not exceeding 60%.
Temperature is also critical. It should be stored in a cool place to avoid hot topics. Due to high temperature or its volatilization, it may accelerate and even cause decomposition reactions. It is recommended that the storage temperature be between 2-8 ° C.
Furthermore, the packaging must be tight. It should be packed in glass bottles or special plastic bottles to ensure that it is well sealed to prevent air and water vapor from infiltrating.
During transportation, it is extremely important to prevent shock and collision. Because it is a fragile bottled chemical, bumps and collisions may cause packaging to break and materials to leak. The transportation vehicle must drive smoothly, and when the road is bumpy, it should pass slowly.
At the same time, it should be protected from direct sunlight. Light may cause photochemical reactions to change the chemical structure and properties. Vehicles should be equipped with shading facilities, such as tarpaulins, etc., and the transportation period should also be selected when the light is weak in the morning and evening.
In addition, transportation and storage personnel need professional training, familiar with the properties of the chemical and emergency treatment methods. In the event of an accident such as a leak, it can respond promptly and correctly to ensure the safety of personnel and the environment from contamination.

I look at the "4 - Bromo - 1 - Iodo - 2 - (Trifluoromethyl) Benzene" you are inquiring about, which is an organic compound. Its market price range is difficult to determine, due to the interaction of many factors.
First, the cost of raw materials has a great impact. The price of bromide, iodide and trifluoromethyl-containing raw materials required for the preparation of this compound fluctuates erratically. If raw materials are scarce or production is difficult, the price will rise; conversely, if raw materials are abundant, the price may drop.
Second, the simplicity of the preparation process also affects its price. If delicate and complex synthesis steps are required, such as multi-step reactions, harsh reaction conditions, such as high temperature, high pressure, special catalysts, etc., the cost will increase and the price will also be high; if the process is simple and efficient, the cost may be reduced, and the price will also be lower.
Third, the market supply and demand situation is the key. If many industries, such as medicine, material science, etc., have strong demand for it, but the supply is limited, the price will be high; if the demand is weak and the supply is excessive, the price will easily fall.
Fourth, the product purity requirements are also related to the price. High-purity products are difficult to prepare, the cost is high, and the price is naturally expensive; ordinary purity products, the price may be relatively low.
Combined with various factors, the price of this compound may range from tens to hundreds of yuan per gram, but this is only a rough estimate. The actual price should be carefully investigated according to specific market conditions, transaction quantity and quality.
