N-methyl-imidazole-4-carboxylic acid, this substance is in the state of white to off-white crystalline powder. Its melting point is quite high, about 210-214 ° C. Due to the strong interaction in the molecule, the lattice energy is large, and high energy is required to destroy the lattice to cause melting.
Its solubility is quite characteristic, soluble in water, because there are carboxyl groups and imidazole rings in the molecule, which can interact with water molecules through hydrogen bonds. However, it is difficult to dissolve in common organic solvents such as ethyl ether and petroleum ether, because its polarity is relatively large, and the interaction force with non-polar organic solvents is weak.
In terms of stability, it is relatively stable under normal conditions. In case of strong acid and alkali, it can react. Due to its acidic carboxyl group, it can be neutralized with bases; imidazole ring has certain basic and nucleophilic properties, and can interact with acids or electrophilic reagents. When heated, high temperature will cause decomposition, and high temperature will destroy the chemical bonds in the molecule.
This substance is widely used in the field of organic synthesis and is often used as a key intermediate for the preparation of a variety of nitrogen-containing heterocyclic compounds. By means of its carboxyl group and imidazole ring, complex organic molecular structures can be constructed by esterification, amidation and other reactions.

The synthesis method of N-methyl-imidazole-4-carboxylic acid has been known for a long time. There are many methods and each has its own strengths.
One can be obtained by reacting imidazole-4-carboxylic acid with methylating reagents. Among them, methylation reagents are commonly used, such as iodomethane, dimethyl sulfate and the like. First put imidazole-4-carboxylic acid in a suitable solvent, such as dichloromethane, N, N-dimethylformamide, etc., then slowly add methylating reagents and stir the reaction at a certain temperature. When reacting, pay attention to the control of temperature. If it is too high, the side reactions will increase, and if it is too low, the reaction rate will be slow. After the reaction is completed, the pure N-methyl-imidazole-4-carboxylic acid can be obtained through extraction, washing, drying, column chromatography and other steps.
Second, the corresponding nitrogen-containing heterocyclic compound is used as the starting material and prepared through a multi-step reaction. For example, the imidazole ring is constructed with specific raw materials first, and then methyl and carboxyl groups are introduced. Although this approach has many steps, the reaction steps and conditions can be flexibly adjusted according to the characteristics of the desired product to achieve the purpose of precise synthesis. During the synthesis process, each step of the reaction requires fine operation, and the reaction conditions are strictly controlled. Such as the proportion of reactants, reaction temperature, reaction time, etc., all affect the purity and yield of the product.
Third, there is also a method of catalytic reaction. Select suitable catalysts, such as some metal catalysts or organic small molecule catalysts, to promote the efficient progress of the reaction. This method can improve the selectivity and rate of the reaction, reduce the generation of by-products, and provide a more convenient way for synthesis. However, the choice and dosage of catalysts are quite critical, and it is necessary to explore the best reaction conditions through many experiments.
All kinds of synthesis methods have their own advantages and disadvantages. It is necessary to choose carefully according to actual needs and conditions to efficiently prepare N-methyl-imidazole-4-carboxylic acid.

Today I have a question, what is the price of N-methyl-imidazole-4-carboxylic acid in the market? This is a commonly used product in fine chemicals. The change in price often depends on factors such as supply and demand, quality, and source.
In the past, if this product was of ordinary industrial grade and purchased in bulk, the price per kilogram was about several hundred yuan. If the quality is of high quality and reaches the pharmaceutical grade standard, the price will be doubled or several times.
According to the book "Tiangong Kaiwu", although there is no exact price of this chemical, it is the same. The price of materials is related to the difficulty of procurement and the amount of labor. The preparation process of N-methyl-imidazole-4-carboxylic acid requires delicate steps and exquisite materials, which all cause its price to vary.
And the price varies depending on the trade and logistics in various places. In prosperous commercial ports, the logistics is convenient and the supply is sufficient, and the price is flat; in remote places, or due to the difficulty of transshipment, the price is slightly higher. Therefore, if you want to know the exact price, you can only get the current appropriate price when you consult chemical material merchants.

N-methyl-imidazole-4-carboxylic acid should be stored in a cool, dry and well-ventilated place. This is because the substance may be quite sensitive to temperature and humidity, high temperature, humid environment, or cause its properties to change, affecting its quality and effectiveness.
When stored, when away from fire and heat sources, cover it because it may have certain flammability, in case of open flames, hot topics may be dangerous. It should also be stored separately from oxidizing agents, acids, alkalis, etc., and must not be mixed. Due to its active chemical properties, contact with such substances may easily cause chemical reactions, cause material damage, or even cause safety accidents.
The package must be sealed to prevent it from interacting with moisture, oxygen and other components in the air. If the package is damaged, it should be replaced in time, and the exposed materials should be properly disposed of to avoid the risk of deterioration.
It is also important to regularly check the storage status to see if the package is damaged and the material has deteriorated. If there is any abnormality, deal with it quickly to ensure that the material is in good condition. In this way, the N-methyl-imidazole-4-carboxylic acid can be kept for a long time for later use.
