The common synthesis method of 6-bromo-2-methyl-1H-benzimidazole has attracted much attention in the field of organic synthesis. The synthesis method follows several paths.
One is often to use o-phenylenediamine and bromoacetic acid derivatives as starting materials. The o-phenylenediamine has an active amino group, and the bromoacetic acid derivative contains an active halogen atom. Under suitable reaction conditions, the two first undergo a condensation reaction, and the amino group interacts with the carboxyl-derived group to form an intermediate product. This step often requires a suitable solvent, such as ethanol, dichloromethane, etc., to help the reactants fully contact, and the temperature also needs to be precisely controlled. Generally, under mild heating conditions, about 50-80 ° C, the reaction can be promoted smoothly. Subsequently, the intermediate product is cyclized to form the core structure of benzimidazole. This cyclization step may require the assistance of a catalyst, such as some Lewis acids, to reduce the activation energy of the reaction and improve the reaction rate and yield.
Second, there are also nitroaniline compounds as starters. First, nitroaniline is reduced to convert the nitro group into an amino group to obtain the corresponding o-phenylenediamine derivatives. This reduction process is often carried out by a system composed of iron powder, zinc powder and other metals and acids, or by catalytic hydrogenation. Then, the obtained o-phenylenediamine derivatives are reacted with brominating reagents and methylating reagents in sequence. Bromine sources such as liquid bromine and N-bromosuccinimide (NBS) can be selected for bromine reaction, and bromine atoms are introduced under appropriate solvents and reaction conditions. The methylation reaction uses iodomethane, dimethyl sulfate, etc. as methylating reagents, and the introduction of methyl is completed under basic conditions, such as the presence of potassium carbonate, sodium hydroxide and other bases, resulting in 6-bromo-2-methyl-1H-benzimidazole.
In addition, there are other synthetic paths, but the above two are relatively common methods. During the synthesis process, the conditions of each step of the reaction are finely regulated, which has a great impact on the purity and yield of the product. In practice, chemists often choose the appropriate synthesis route according to the availability of raw materials, cost and the requirements of the target product.

6-Bromo-2-methyl-1H-benzimidazole is an organic compound, and its market price fluctuates due to various factors, making it difficult to give a fixed value.
The price of this compound is first influenced by supply and demand. If the market demand for it is strong and the supply is relatively short, the price will rise; conversely, if the demand is low and the supply is sufficient, the price may decline.
Furthermore, the production cost has a great impact. The cost of raw materials, the complexity of the production process and energy consumption are all related to the cost. If the scarcity of raw materials is high, or the production process requires high technology and high-cost equipment, the price of the product will be high.
Purity is also a key factor. The price of high-purity 6-bromo-2-methyl-1H-benzimidazole is usually higher than that of low-purity products due to the need for finer purification processes.
In addition, the market competition situation also plays a role. If there are many market participants and the competition is fierce, the price may be favorable in order to compete for share; conversely, under the monopoly or oligopoly situation, the price may be more manipulative.
According to past market conditions, the price per gram of low-purity crude products may range from a few yuan to tens of yuan; while the price of high-purity fine products may reach more than 100 yuan per gram, or even higher, depending on the specific purity and market conditions. However, this is only a rough estimate. The actual price must be monitored in real time through channels such as chemical product trading platforms and supplier quotations in order to be accurately known.
