In agriculture, rodent infestation often has a serious impact on the growth and yield of crops. Rats such as voles will gnaw on the seeds, seedlings, rhizomes and fruits of crops, resulting in a sharp decrease in crop yield and quality. Bromodiazolone can attract mice to eat by adding it to the poison bait. After the mice eat the poison bait, the drug will work in their bodies, inhibiting the activity of vitamin K1 and hindering the normal coagulation of blood. Over time, the mice will gradually die due to internal bleeding, thus effectively controlling the number of rodent infestations in the farmland, ensuring the robust growth of crops and improving agricultural yield.
In the field of warehousing, warehouses store a large amount of food, supplies, etc. The presence of rats not only steals food, bites the packaging of goods, but also may spread diseases. The use of bromodiazolone made of poison bait can effectively kill rats in warehouses, avoid damage to food and supplies by rats, and reduce economic losses.
In some public health places, such as residential areas, hospitals, schools, etc., the presence of rats will pose a threat to people's living environment and health. Bromodiazolone can be used in rodent control work in these areas to reduce the risk of rats spreading diseases and maintain public health safety.
However, caution must be used when using bromodiazolone. Due to its strong toxicity, it not only has a lethal effect on mice, but also may have serious consequences for other non-target animals, such as birds, livestock, etc. If accidentally eaten by mistake. Therefore, during use, it is necessary to strictly follow relevant regulations and safety operating procedures to place the poison bait in a suitable position to avoid unnecessary harm to the surrounding environment and other organisms.

Looking at its properties, it usually shows [specific form of [specific color], such as powder or crystal, etc.], which is conducive to its preservation and use in a specific environment. Its melting point is very critical, about [X] ℃, the melting point of this characteristic determines its state transition node when heated, and it will gradually transform from solid to liquid at the corresponding temperature, which is of great significance for controlling the reaction temperature and the change of material form in chemical production.
In terms of solubility, it exhibits different solubility in some common organic solvents. It has a certain solubility in [Organic Solvent Name 1] and can partially dissolve to form a uniform dispersion system, while it has poor solubility in water and is almost insoluble. This difference in solubility is closely related to its molecular structure. The hydrophobic groups in the molecule make it tend to disperse in non-polar or weakly polar organic solvents, while it has poor affinity for polar water.
In terms of density, it is about [X] g/cm ³. This density value makes it possible to participate in the mixing system. According to the Archimedes principle, it will have corresponding floating behavior in a specific liquid environment, which has an impact on the distribution and separation of substances in the liquid phase reaction system.
In addition, it also has a certain degree of volatility. In a normal temperature environment, it will slowly evaporate a small amount of molecules to the surrounding space. Although the volatilization rate is relatively slow, when placed in a closed space for a long time, its concentration will increase in the space due to volatilization. This requires attention in storage and use scenarios to avoid concentration changes caused by volatilization affecting its performance or causing other potential effects.

To prepare 2- (2,4-diethylphenyl) -3H-indole-4-acetic acid, the following ancient method can be used.
First take appropriate starting materials, such as benzene derivatives containing corresponding substituents and indole-related precursors. Taking benzene derivatives as an example, a specific substitution reaction needs to be carried out to introduce 2,4-diethylphenyl. This step can be achieved by electrophilic substitution reaction. Select appropriate halogenated ethane and benzene derivatives. Under the catalysis of lewy acid, the ethyl group replaces the hydrogen on the benzene ring and is precisely positioned at the 2,4 position.
After obtaining 2,4-diethylphenyl-substituted benzene derivatives, condensation reactions are carried out with indole precursors. This reaction may need to be carried out in an alkaline environment and an appropriate organic solvent, so that the two are connected to form an indole ring structure. The reaction conditions need to be carefully regulated, and the temperature and the proportion of reactants are all related to the formation of the product.
After the initial construction of the indole ring is completed, the acetate group is introduced at the 4th position of the indole ring. This can be carried out by means of a suitable acylating agent, such as acetic anhydride or acetyl chloride, under the action of a catalyst. During the process, attention should be paid to the selectivity of the reaction to ensure that the acetate group is accurately connected to the 4th position.
After the reaction is completed, the product is separated and purified. Extraction, distillation, recrystallization, etc. can be selected according to the physical and chemical properties of the product and impurities. During extraction, a suitable organic solvent is selected to separate the product from impurities; distillation is achieved by different boiling points; recrystallization can obtain a pure 2- (2,4-diethylphenyl) -3H-indole-4-acetic acid product according to the solubility difference of the product in different solvents.

I think what you are asking is about the price range of 2- (2,4-diethylphenyl) -3H-indole-4-methylnitrile in the market. However, I am in the book of "Tiangong Kaiwu", and there was no such fine chemistry at that time, so it is difficult to determine its price.
In today's world, the price of chemical products often varies due to many factors. First, the price of raw materials. If the raw materials required to make 2- (2,4-diethylphenyl) -3H-indole-4-methylnitrile are scarce or expensive, the price of the finished product is also high. Second, the complexity of the process. If the process of preparing this compound is complicated, requires exquisite equipment, exquisite technology, and requires more energy consumption, its cost will increase, and the price will also rise. Third, market supply and demand. If there are many people who want it, and there are few people who supply it, the price will increase; on the contrary, if the supply exceeds the demand, the price will be depressed.
Although I cannot confirm the price, in today's world, if you want to know the price range of this chemical, you can consult the merchants in the chemical market, check the database of chemical product prices, or ask the experts in the chemical industry. They will be able to tell you the approximate price range according to the current situation.
