The chemical synthesis of 1-methyl-4-formyl imidazole is an important topic in the field of organic synthesis. This compound has wide application prospects in many fields such as medicinal chemistry and material science, so it is of great significance to explore its efficient synthesis method.
In the past, many parties studied the synthesis of this compound, and the common methods were as follows. First, 1-methylimidazole was used as the starting material, and formyl groups could be introduced through Vilsmeier-Haack reaction. In this reaction, N, N-dimethylformamide (DMF) is mixed with phosphorus oxychloride (POCl < unk >) to form Vilsmeier reagent, and 1-methylimidazole is reacted with it at an appropriate temperature and reaction time to generate 1-methyl-4-formyl imidazole. In the specific operation, DMF and POCl < unk > are mixed at low temperature to make the two fully act to form an active intermediate, then 1-methylimidazole is slowly added, heated to a suitable temperature, and the reaction is continuously stirred for several hours. After the reaction is completed, the post-treatment operation, such as quenching with water, neutralizing with lye, organic solvent extraction, column chromatography separation, etc., can obtain a purified product.
Second, 4-methylimidazole is also used as a raw material to oxidize methyl to carboxyl group first, and then convert it into formyl group through reduction reaction. The oxidation step often uses a strong oxidizing agent, such as potassium permanganate, to oxidize the methyl of 4-methylimidazole to carboxyl group under basic conditions to obtain 4-carboxyl-1-methylimidazole. Then, a suitable reducing agent, such as sodium borohydride-cerium trichloride (NaBH-CeCl 🥰) system, is selected to reduce the carboxyl group to formyl group at low temperature, and the target product 1-methyl-4-formylimidazole can be obtained through separation and purification. Although the steps of this method are slightly complicated, the reaction conditions of each step are relatively mild and the yield is considerable.
Third, it can also be synthesized by the construction of imidazole rings. With appropriate nitrogen and carbon-containing raw materials, imidazole rings are constructed under the action of catalysts, and methyl and formyl groups are introduced at the same time. This method requires precise design of reaction routes and selection of suitable catalysts. Although it is challenging, it is expected to achieve a high atomic economy synthesis path, opening up a new path for the synthesis of 1-methyl-4-formyl imidazole.
Each of the above methods has advantages and disadvantages. In practical application, the optimal synthesis method should be selected based on factors such as specific needs, availability of raw materials, and cost considerations.

1-Methyl-4-formylimidazole is a chemical substance, and many matters need to be paid attention to during storage and transportation.
First, when storing, it should be placed in a cool, dry and well-ventilated place. This is due to its nature or fear of moisture and heat. If it is placed in a warm and humid place, it may cause deterioration. For example, if it is placed in a hot and humid corner, or it may cause changes in its chemical structure, which will affect its quality.
Second, it needs to be stored separately from oxidants, acids, bases, etc. Because of its active chemical properties, it is easy to react chemically or cause danger when it encounters various such substances. If it coexists with strong oxidizing agents, there may be a risk of combustion or explosion.
Third, the storage container must be tightly sealed. To prevent it from evaporating and escaping, one will damage itself, and the other may be harmful to the environment and the human body. The sealed device can ensure its stability.
As for transportation, ensure that the packaging is complete and the loading is secure. During transportation, avoid vibration, impact and friction to prevent the packaging from being damaged and causing leakage of 1-methyl-4-formyl imidazole.
At the same time, the transportation tool should also be clean and dry, and there should be no residual other chemicals to avoid adverse reactions with it. And transport personnel need to be familiar with its characteristics and emergency treatment methods. In case of accidental leakage, etc., it can be properly disposed of in time to avoid disaster. In this way, 1-methyl-4-formyl imidazole is safe during storage and transportation.

1-Methyl-4-formyl-imidazole, this substance is in the market, and its price is really difficult to determine. Its price often changes due to various reasons, such as differences in production sources, special quality of products, and demand for supply.
Looking at the past, if the production source is wide and the supply is sufficient but the demand is not abundant, the price may become more common. If the source is narrow, the preparation is difficult to increase, and there are many people seeking it, the price will rise. In addition, those with pure quality are often higher than those with less quality.
Looking for the range of its price, under normal circumstances, it ranges from tens to hundreds of dollars per gram. However, in case of changes in market conditions, such as the price of raw materials, the new method of preparation, or the use of domain expansion, the price can be changed. If you want to know the exact price, you should inquire in detail from the market, or ask the industry about it, you can get the current real price, which is almost the same.
