Furthermore, in the field of organic synthetic chemistry, this compound is often used as a key raw material or intermediate to participate in the construction of complex organic molecules. Chemists use various organic reactions, such as nucleophilic substitution and cyclization, to create organic compounds with diverse structures starting from 5-bromo-2-methyl-1H-benzo [d] imidazole, expanding the boundaries of organic synthesis, and laying the foundation for the development of new materials and new drugs.

The common methods for the synthesis of 5-bromo-2-methyl-1H-benzo [d] imidazole are as follows.
First, the starting materials are o-phenylenediamine and methyl bromopyruvate. First, the reaction of o-phenylenediamine and methyl bromopyruvate in a suitable solvent, such as ethanol, under the condition of heating and reflux. In this reaction, the amino group of o-phenylenediamine reacts with the carbonyl group and bromine atom of methyl bromopyruvate to form an intermediate product. Subsequently, the intermediate product is cyclized under acidic or basic conditions to obtain 5-bromo-2-methyl-1H-benzo [d] imidazole. The raw materials for this method are relatively easy to obtain, but the reaction steps are slightly more, and the reaction conditions need to be carefully controlled to improve the yield and purity of the product.
Second, 2-methyl-1H-benzo [d] imidazole is used as the starting material to introduce bromine atoms through the bromination reaction. Bromine or N-bromosuccinimide (NBS) can be used as the bromination reagent. If bromine is used as the reagent, an appropriate amount of catalyst, such as iron powder, is added to the glacial acetic acid and other solvents to heat the reaction. The electrophilic substitution reaction occurs at a specific position on the benzene ring of 2-methyl-1H-benzo [d] imidazole, and the bromine atom replaces the hydrogen atom to form the target product. When using NBS, it often reacts in solvents such as carbon tetrachloride. The reaction conditions are relatively mild, the requirements for reaction equipment are slightly lower, and the selectivity is better, and bromine atoms can be introduced at the target position more accurately.
Third, the coupling reaction catalyzed by transition metals. For example, a suitable halogenated benzene derivative is used as a raw material with borate esters or boric acid derivatives containing imidazole structure, and under the action of transition metal catalysts such as palladium, it is reacted in a basic environment and a specific organic solvent. The reaction conditions of this method are relatively strict, requiring precise control of factors such as catalyst dosage, reaction temperature and time. However, its advantage is that it can efficiently construct the structure of the target molecule, especially for scenarios that require high product purity and structural accuracy.

The price of 5-bromo-2-methyl-1H-benzo [d] imidazole in the market is difficult to determine. The price of this compound often varies due to various factors.
First, the purity is related to the price. If the purity is extremely high and almost flawless, it is suitable for delicate experiments or high-end industries, and the price is high; while the purity is slightly lower, it is only suitable for ordinary basic research or general use, and the price is slightly lower.
Second, the trend of supply and demand is also the key. If there is a strong demand for this product in the market and the supply is limited, it is like a rare treasure, and the price will rise; on the contrary, if the supply exceeds the demand, such as a crucian carp crossing the river, the price will easily fall.
Third, the difficulty and cost of production also have an impact. If the preparation process is complicated, rare raw materials are required, or the equipment and process requirements are strict, and the cost is high, the price will also be expensive; if the preparation is relatively simple and the cost is controllable, the price may be close to the people.
According to past market conditions, its price fluctuates greatly. Those with higher purity may reach tens or even hundreds of yuan per gram; while those with slightly lower purity may range from only a few yuan to tens of yuan per gram. However, this is only an approximate number, and the market is changing rapidly. The current price cannot be broken for tomorrow's price. To know the exact price, you need to consult the chemical reagent supplier in detail, or check the recent transaction price on the relevant trading platform to obtain a more accurate figure.

5-Bromo-2-methyl-1H-benzo [d] imidazole, this is an organic compound. Its storage conditions are quite important, related to its quality and stability.
In the context of "Tiangong Kaiwu", although there is no record of this specific compound, the ancients also have a lot of wisdom in material preservation, which can be used for reference.
As far as general organic compounds are concerned, the first priority is to avoid light. Light can often cause chemical reactions, causing them to decompose or deteriorate. Therefore, it should be hidden in a dark room, or in an opaque container to avoid direct sunlight.
Secondly, temperature is also the key. It should be placed in a cool place to avoid high temperature environment. High temperature will accelerate the movement of molecules, promote their reaction, and cause stability damage. Usually a low temperature environment of 2-8 ° C is appropriate. If conditions are not available, it should also be placed in a place where the temperature is relatively stable and not too high.
Furthermore, moisture resistance is also indispensable. Moisture can participate in many chemical reactions, affecting the purity and properties of compounds. It should be stored in a dry place or placed in a container with a desiccant to keep the environment dry.
In addition, attention should be paid to isolating the air. Oxygen, carbon dioxide and other components in the air may react with compounds. Sealed containers can be used to reduce contact with air to keep its chemical properties stable. < Br >
When storing, also pay attention to separate from other chemicals to avoid interaction and ensure their quality and safety. In this way, 5-bromo-2-methyl-1H-benzo [d] imidazole can be properly stored to maintain its properties for a long time.
