What are the physical properties of Benzimidazole, 5-iodo-2-methyl-?
5-Iodine-2-methylbenzimidazole is an organic compound. It has the following physical properties:
Viewed at room temperature, 5-iodine-2-methylbenzimidazole is mostly solid or powdery, and the color state is usually white to light yellow. This is due to the conjugation of the benzimidazole ring with iodine and methyl in the molecular structure and the electronic effect.
In terms of melting point, the compound has a specific melting point range, but the exact value varies depending on the purity and measurement conditions, about 180-200 ° C. The melting point is determined by the intermolecular force. The rigid structure of the benzimidazole ring and the relatively large atomic weight of the iodine atom enhance the intermolecular force, and a higher temperature is required to destroy the lattice, resulting in a higher melting point.
In terms of solubility, 5-iodine-2-methyl benzimidazole has better solubility in organic solvents than water. Its molecule has certain hydrophobicity due to the presence of benzimidazole ring and iodine and methyl. Common organic solvents such as dichloromethane, chloroform, and N, N-dimethylformamide (DMF) have a certain solubility. In dichloromethane, due to the adaptation of the intermolecular force between the two, the dissolution state is quite good. In water, because of its hydrophobicity and weak interaction between water molecules, the solubility is very low.
Density is also an important physical property. Although the exact density data also varies depending on the measurement conditions, roughly speaking, its density is higher than that of water. Due to the type and number of atoms in the molecule, iodine atoms are relatively large in atomic weight and mass, resulting in an increase in unit volume mass, so the density is greater than that of water.
In addition, 5-iodine-2-methyl benzimidazole is relatively stable in chemical properties at room temperature and pressure. However, in case of high temperature, strong oxidant or specific chemical reaction conditions, it can react. Because benzimidazole ring and iodine and methyl can participate in a variety of organic reactions, this is related to the physical properties.
Is Benzimidazole, 5-iodo-2-methyl- chemically stable?
5-Iodine-2-methylbenzimidazole is a chemical substance with relatively stable properties. Looking at its structure, the benzimidazole ring system endows it with certain rigidity and conjugation stability. Although the introduction of the 5-position iodine atom increases the weight and steric resistance of the molecule, it stabilizes the molecular structure to a certain extent because the lone pair electrons can participate in the conjugation. The existence of the 2-position methyl group changes the electron cloud distribution of the molecule, but does not significantly damage the overall stability.
From the perspective of chemical environment, the substance can maintain its own structure in common organic solvents. In neutral or weak acid-base environments, it is not prone to hydrolysis, ring opening and other reactions. Due to the aromaticity of benzimidazole ring, it has a certain resistance to pyrolysis, and the structure can still survive under moderate heating conditions. However, when encountering strong oxidizing agents or specific harsh reaction conditions, its stability may be challenged, or changes may occur such as substitution of iodine atoms and oxidation of ring systems. In general, the chemical properties of 5-iodine-2-methyl benzimidazole are relatively stable under conventional chemical operations and general storage environments.
What are the synthesis methods of Benzimidazole, 5-iodo-2-methyl-?
To prepare 5-iodine-2-methylbenzimidazole, the following ancient method can be used.
First of all, o-phenylenediamine and acetic acid are used as starting materials. In the reaction kettle, add o-phenylenediamine and acetic acid in an appropriate proportion. The ratio of the two needs to be accurately measured, which is related to the reaction effect. Heating causes the reaction to start, and the temperature should be raised slowly to a specific temperature range and maintained. In this process, o-phenylenediamine and acetic acid undergo condensation reaction to initially form 2-methylbenzimidazole. This reaction requires attention to the reaction time, and timely monitoring with instruments to observe the progress of the reaction.
Then the iodization reaction of 2-methylbenzimidazole is carried out. In the reaction system, add an appropriate amount of iodizing reagent, such as iodine elemental substance in combination with an appropriate oxidizing agent. Control the reaction environment, such as temperature, pH and other conditions. If the temperature is too high or too low, the reaction can cause deviation, pH discomfort, and also affect the purity and yield of the product. During the reaction, pay close attention to the changes in the system. After the reaction is completed, use suitable separation and purification methods, such as extraction, crystallization, column chromatography, etc., to obtain pure 5-iodine-2-methylbenzimidazole.
Or there are other methods. A specific intermediate can be prepared by reacting o-phenylenediamine with halogenated acetic acid derivatives first, and then the subsequent conversion and iodization steps can finally obtain the target product. However, all steps need to adhere to the operating specifications and control the reaction conditions, so that the reaction can be smooth and the expected 5-iodine-2-methylbenzimidazole can be obtained.
