1-Benzyl-4-iodoimidazole is one of the organic compounds. Its physical properties are particularly important and are listed as follows:
Looking at its properties, under room temperature, 1-benzyl-4-iodoimidazole is often in a solid state, which is caused by the force between molecules, resulting in a relatively stable structure. Its color may be white to light yellow. The appearance of this color is due to the characteristics of molecular light absorption and reflection.
When it comes to melting point, 1-benzyl-4-iodoimidazole has a specific melting point range, due to the change in molecular arrangement and interaction when heated. Accurate determination of the melting point can help to distinguish the purity of this compound. The melting point of pure products is relatively fixed, and the existence of impurities causes the melting point range to widen or change the melting point value.
In terms of solubility, 1-benzyl-4-iodoimidazole behaves differently in organic solvents. In polar organic solvents such as dichloromethane, N, N-dimethylformamide (DMF), there is a certain solubility. This is because the solvent and the solute molecules can form interactions such as van der Waals force and hydrogen bonds, so that the solute molecules are dispersed in the solvent. However, in water, its solubility is very small. In its molecular structure, the hydrophobic benzyl group and the iodoimidazole ring account for a large proportion, and the interaction with water molecules is weak, and it is difficult to dissolve in the water phase with strong polarity.
In addition, the density of 1-benzyl-4-iodoimidazole is also one of its physical properties. Density reflects the mass of its unit volume and is related to the size and arrangement of molecules. Accurate determination of density is a key link in chemical, pharmaceutical and other application fields, such as material measurement and reaction system ratio.
The physical properties of 1-benzyl-4-iodoimidazole, such as properties, melting point, solubility, density, etc., are of critical significance for the identification, separation, purification, and application of compounds in different fields. It is also the basis for in-depth research and rational use of this compound.

The synthesis of 1-benzyl-4-iodoimidazole is very common. The common one is to take imidazole as the base, first through benzylation, and then iodization. When benzylated, imidazole and benzyl halide, such as benzyl chloride or benzyl bromide, are catalyzed by bases, such as potassium carbonate, sodium hydroxide, etc., in suitable solvents, such as acetonitrile, N, N-dimethylformamide, heated and stirred to obtain 1-benzylimidazole. In this step, the role of the base is to grab the hydrogen of the imidazole, so that it can form negative ions, and then nucleophilic substitution with the benzyl halide to form 1-benzylimidazole.
Wait for 1-benzyl imidazole to obtain it, and then perform iodization. The method of iodization can use iodine element and oxidant, such as hydrogen peroxide, sodium nitrite, etc., to react in suitable solvents, such as glacial acetic acid and dichloromethane. The function of the oxidant is to convert the iodine element into an active iodine positive ion, and then electrophilic substitution occurs with the 4-position of 1-benzyl imidazole to obtain 1-benzyl-4-iodoimidazole.
Another method uses 4-iodoimidazole as the starting material to react with the benzylating agent. In addition to the above benzyl halide, benzyl alcohol can also be used with an acid catalyst, such as p-toluenesulfonic acid, under heating conditions, through nucleophilic substitution reaction to obtain the target product 1-benzyl-4-iodoimidazole. In this process, the acid catalyst can activate the hydroxyl group of benzyl alcohol, making it easy to be attacked by the nitrogen atom of 4-iodoimidazole, and complete benzylation.
Another way is to design a multi-step reaction route. Starting from a simple raw material, an imidazole ring is gradually constructed, and benzyl and iodine atoms are introduced at the same time. However, this approach is relatively complicated and requires fine control of the reaction conditions and the purity of the intermediate, but it is also an optional way to synthesize 1-benzyl-4-iodoimidazole. All methods have their own advantages and disadvantages. In actual synthesis, it is necessary to weigh the availability of raw materials, the difficulty of reaction conditions, and the purity requirements of the product.

1-Benzyl-4-iodoimidazole is in the market, and its price range is difficult to determine. The price of this compound often changes for many reasons.
First, the source and quality of the material. If the raw material is easy to harvest and of good quality, its price may be relatively easy; on the contrary, if the raw material is rare or difficult to obtain, the price will increase.
Second, the complexity of the process. If the preparation method is complicated, multiple processes are required, many agents are used, and the energy consumption is also large, the cost will rise, and the price will also be higher.
Third, the supply and demand of the city. If there are many applicants, but there are few suppliers, the price will rise; if the supply exceeds the demand, the price may decline.
Fourth, the seller and the purchase quantity. Different vendors have different pricing due to differences in business strategies and cost and interest. And if the buyer has a large batch, the seller may give a discount, and the price will be different.
From this perspective, in today's market, the price of 1-benzyl-4-iodimidazole ranges from tens of yuan to hundreds of yuan per gram. However, this is only an approximate number, and the actual price should be based on the actual number obtained by real-time consultation with vendors and chemical trading platforms.

1 - benzyl - 4 - iodoimidazole is a reagent commonly used in organic synthesis. There are many precautions in the use process, and it must be treated with caution.
First, it is related to safety protection. This reagent is toxic and irritating. When operating, you must wear protective clothing, gloves and goggles to prevent the reagent from contacting the skin and eyes. If you come into contact accidentally, you should immediately rinse with plenty of water and seek medical attention as appropriate. And the operation should be carried out in a well-ventilated environment or in a fume hood to avoid inhalation of its volatile aerosol and damage to the respiratory tract.
Second, it involves storage conditions. Store 1 - benzyl - 4 - iodoimidazole in a cool, dry place, away from fire and oxidants. Because it is sensitive to light and heat, it should be stored away from light and can be placed in a brown bottle to prevent deterioration and affect the use effect.
Third, about the chemical reaction characteristics. Its iodine atoms have high reactivity. When participating in the reaction, the reaction conditions should be precisely controlled, such as temperature, reaction time and the proportion of reactants. If the temperature is too high, side reactions may occur, reducing the purity and yield of the product; if the reaction time is too short, the reaction may be incomplete; if the proportion of reactants is improper, it will also affect the reaction process and product formation.
Fourth, about the post-treatment operation. After the reaction is completed, the system containing 1-benzyl-4-iodoimidazole and its reaction products should be handled with caution. Follow relevant environmental protection and safety regulations, properly dispose of waste to prevent pollution to the environment. For the separation and purification of products, appropriate methods such as column chromatography and recrystallization should be selected according to their characteristics to obtain high-purity products.
