1-Bromo-2-fluoro-4-iodobenzene, with a content of 98%, its physical properties are as follows:
This compound is mostly liquid at room temperature. Due to the presence of halogen atoms in its molecular structure, the intermolecular force is enhanced, and the relative molecular mass is also larger. Therefore, the boiling point is higher. The specific boiling point value will vary depending on the precise measurement conditions, and it is generally in a higher temperature range. Its density is higher than that of water because the relative atomic mass of halogen atoms is larger, which makes the compound heavier per unit volume mass and will sink to the bottom when mixed with water.
In terms of appearance, pure 1-bromo-2-fluoro-4-iodobenzene is usually a colorless to pale yellow transparent liquid, but the color may change slightly due to factors such as impurities or light. Its solubility is quite special, and its solubility in water is very small. This is because the organic substance is a non-polar or weakly polar molecule, while water is a polar molecule. According to the principle of "similar miscibility", the two are difficult to miscible. However, it is soluble in a variety of organic solvents, such as common ether, dichloromethane, carbon tetrachloride, etc. These organic solvents also have non-polar or weakly polar characteristics, and are similar to 1-bromo-2-fluoro-4-iodobenzene molecules in intermolecular forces, which can be miscible with each other.
In terms of optical properties, the compound may absorb light of specific wavelengths. The specific absorption spectral characteristics can be accurately determined by means of spectral analysis, which is of great significance in the identification and analysis of the compound. In addition, its refractive index also has specific values. The refractive index is related to the molecular structure and density of the substance, which can be used as one of the physical constants of the compound for purity identification and other aspects.

1-Bromo-2-fluoro-4-iodobenzene, with a content of 98%. This is a chemical substance. When storing, many things need to be paid attention to.
First, it is necessary to choose a suitable place. This substance should be stored in a cool, dry and well-ventilated place. Due to high temperature, its chemical properties may be changed, causing reactions; excessive humidity may affect its purity or even cause it to deteriorate. If placed in a hot and humid place, it may change unexpectedly.
Second, the packaging must be tight. It should be packed in a sealed container to prevent contact with air, moisture, etc. Because of its activity or high, in contact with external substances, it is easy to cause chemical reactions and damage its quality.
Third, it should be placed separately from other chemical substances. Especially those substances that can react violently with it, such as strong oxidants, strong alkalis, strong acids, etc. If accidentally mixed, once the interaction, or cause combustion, explosion and other disasters.
Fourth, the storage area should be clearly marked. Indicate the name, nature, hazards and other information of the substance, so that the relevant personnel can see at a glance, and be cautious when operating to avoid accidental touch and misuse.
Fifth, regularly check the stored substances. Check whether the packaging is damaged, whether the substance has deteriorated, etc. If there is any abnormality, deal with it immediately to avoid endangering safety and causing unnecessary losses.
All of these are the key points that should be taken seriously when storing 1-bromo-2-fluoro-4-iodobenzene, and must not be negligent, so as not to cause disaster.

There are many different methods for preparing 1-bromo-2-fluoro-4-iodobenzene. Here are a few common ones.
First, 2-fluoro-4-iodoaniline is used as the starting material. First, it is reacted with sodium nitrite and hydrobromic acid at low temperature, and the method of diazotization is performed. This process must be controlled carefully to prevent the decomposition of diazonium salts. After diazotization, the diazonium group is replaced with a bromine atom with an appropriate reducing agent, such as hypophosphoric acid or stannous ions, etc., and then 1-bromo-2-fluoro-4-iodobenzene is obtained. Although this approach is complicated, if it is properly operated, a higher yield can be obtained.
Second, 2-fluoro-4-iodobenzoic acid is used as the starting material. First, it is converted into the corresponding acid chloride, which can be achieved by reagents such as thionyl chloride. Then the acid chloride interacts with halogenated reagents such as cuprous bromide, and through Sandmeyer reaction, bromine atoms are introduced into the benzene ring, and the carboxyl group is decarboxylated at the same time, and 1-bromo-2-fluoro-4-iodobenzene can also be obtained. This method requires careful handling of the preparation of acid chloride, because it has strong activity and corrosiveness.
Or, using 1-bromo-2-fluorobenzene as raw material, iodine atoms are introduced through iodization reaction. Usually, iodine sources such as iodine elemental substance and oxidants (such as cerium ammonium nitrate, etc.) can be added to an appropriate solvent, such as N, N-dimethylformamide, to promote iodine atoms to selectively replace hydrogen atoms at specific positions on the benzene ring, and then obtain the target product. In this process, it is necessary to pay attention to the influence of reaction conditions on the selectivity of substitution positions, and strive to obtain high-purity 1-bromo-2-fluoro-4-iodobenzene.
There are many methods for preparing 1-bromo-2-fluoro-4-iodobenzene, each with advantages and disadvantages. In practice, the appropriate method should be carefully selected according to the availability of raw materials, the difficulty of controlling reaction conditions, and the purity requirements of the target product.

1-Bromo-2-fluoro-4-iodobenzene, with a purity of 98%, the market price range is difficult to determine. Due to the market conditions, it often changes with many factors.
First, the price of raw materials has a great impact. If the price of bromine, fluorine, iodine and other raw materials required for the production of this compound fluctuates, the price of 1-bromo-2-fluoro-4-iodobenzene will also fluctuate. For example, bromine, if the production area encounters a natural disaster and the output decreases sharply, its price will rise, and the price of this product will also rise.
Second, the trend of supply and demand determines the price. If at a certain time, many pharmaceutical companies or chemical companies have a large increase in demand for 1-bromo-2-fluoro-4-iodobenzene, and the supply is limited, the price will tend to rise; on the contrary, if the supply exceeds the demand, the price will easily fall.
Third, the difficulty of preparation is related to cost and price. The synthesis of this compound may require complex processes and harsh conditions. If the preparation is difficult, the cost will increase, and the price will be expensive. If the process is improved, the difficulty will be reduced, the cost will be reduced, and the price may be lowered.
Fourth, the state of market competition also plays a role. If multiple manufacturers in the city produce this product, the competition is fierce, and there may be price reductions in order to compete for share; if the market is monopolized, or there are few suppliers, the price is easily controlled by a few hands and is at a higher level.
Overall, the price may range from tens to hundreds of yuan per gram, which is difficult to give accurately. It is necessary to observe the changes in various factors in the market in real time to know the exact price range.
