1-methyl-2-imidazolecarboxaldehyde

1 - methyl - 2 - imidazolecarboxaldehyde, that is, 1 - methyl - 2 - imidazole formaldehyde, this is an organic compound with unique chemical properties.
In terms of physical properties, under room temperature, or as a solid, due to the interaction between atoms and groups in the molecule, the melting boiling point has a specific value. In its structure, the imidazole ring is connected to the methyl group and the aldehyde group. Because the aldehyde group has a certain polarity, the compound or some polar solvents have a certain solubility. For example, it is slightly soluble in water, but easily soluble in organic solvents such as ethanol and ether.
In terms of chemical properties, the presence of the aldehyde group gives it significant chemical activity. The classic oxidation reaction can occur. In case of common oxidants, such as potassium permanganate, potassium dichromate, etc., the aldehyde group can be oxidized to a carboxyl group to form 1-methyl-2-imidazole carboxylic acid. This reaction is often an important means of constructing carboxyl functional groups in organic synthesis.
can also occur reduction reaction. Hydrogen, sodium borohydride, etc. are used as reducing agents, and the aldehyde group can be reduced to a hydroxyl group to obtain 1-methyl-2 - (hydroxymethyl) imidazole. This product is widely used in the preparation of imidazole derivatives containing hydroxyl groups.
In addition, aldehyde groups can also participate in nucleophilic addition reactions. For example, with alcohols, acetals can be formed under the catalysis of acids or bases. This reaction is often used in organic synthesis to protect the aldehyde group from unnecessary changes in subsequent reactions. On the imidazole ring, the nitrogen atom has a certain alkalinity due to its lone pair of electrons, which can react with acids to generate corresponding salts. This property is of great significance in regulating the solubility and reactivity of compounds.

1 - methyl - 2 - imidazolecarboxaldehyde is 1 - methyl - 2 - imidazole formaldehyde. The common synthesis method is as follows:
The starting material is 1 - methylimidazole. First, the imidazole is N-methylated with a suitable reagent, such as N - methylation reagent, to obtain 1 - methylimidazole. Then, under suitable reaction conditions, 1 - methylimidazole reacts with reagents that can introduce aldehyde groups.
The method of introducing aldehyde groups is commonly used through the Vilsmeier - Haack reaction. Take 1-methylimidazole, dilute it with a suitable solvent, such as dichloromethane, and slowly add Vilsmeier reagent at low temperature. This Vilsmeier reagent is usually prepared from N, N-dimethylformamide and phosphorus oxychloride. After the dropwise addition is completed, gradually heat up to a suitable temperature, such as 40-60 ° C, and stir the reaction for several times. After the reaction is completed, pour the reaction solution into ice water, neutralize it with an alkali solution, such as sodium carbonate solution, and then extract it with an organic solvent, combine the organic phases, dry it with anhydrous sodium sulfate, remove the solvent by vacuum distillation, and then purify it by column chromatography. 1-methyl-2-imidazole formaldehyde can be obtained.
There are also those who use 1-methyl-2-halo imidazole as raw material to make Grignard reagent first, then react with formaldehyde or paraformaldehyde, and then hydrolyze and other steps to obtain the target product 1-methyl-2-imidazole formaldehyde. However, this route needs to pay attention to the strict preparation conditions of Grignard reagent, and anhydrous and anoxic is a necessary condition. During the synthesis process, each reaction step needs to strictly control the reaction conditions, such as temperature, time, reagent dosage, etc., in order to obtain 1-methyl-2-imidazole formaldehyde with higher yield and purity.

1-Methyl-2-imidazole formaldehyde, the price of this substance in the market is difficult to judge. The price of the cover often changes for various reasons, and it is difficult to determine its fixed number.
First, the price of raw materials has a great impact on the cost of 1-methyl-2-imidazole formaldehyde. If the price of the various raw materials required for its preparation fluctuates, the price of 1-methyl-2-imidazole formaldehyde will also change accordingly. If the raw materials are abundant and the supply exceeds the demand, the price may decline; conversely, if the raw materials are scarce and the supply exceeds the demand, the price will rise. < Br >
Second, the preparation method and the coarse process are also related to its price. If the preparation method is simple and easy to implement, and the process is mature, the cost can be reduced, and the price may be close to the people; however, if the preparation method is complicated and requires high-end equipment and exquisite skills, the cost will increase greatly, and the price will also be high.
Third, the supply and demand of the market is the key to pricing. If the market demand for this product is strong and the supply is limited, the price will be high; if the demand is weak and the supply is excessive, the price will inevitably fall.
Fourth, the difference between producers also makes the price different. A well-known large factory, due to its brand reputation and excellent quality, its price may be higher than that of ordinary small factories.
And the market price often changes at any time, and today's price may not be applicable to tomorrow. In order to know the exact market price of 1-methyl-2-imidazole formaldehyde, it is necessary to observe the market dynamics in real time and consult industry experts, or you can get a glimpse.

1 - methyl - 2 - imidazolecarboxaldehyde is 1 - methyl - 2 - imidazole formaldehyde, which is an organic compound. Its storage conditions are very critical, related to its quality and stability.
When stored, the first environment is dry. If it is in a humid place, it is easy to be disturbed by water vapor or cause reactions such as hydrolysis, which will damage its structure and purity. Therefore, it should be placed in a dryer or in a storage area with a desiccant to keep the environment dry and less wet.
The temperature cannot be ignored. It should be stored in a cool place to avoid high temperature hot topic. Due to high temperature, its molecular activity can be enhanced, triggering adverse reactions such as decomposition and polymerization. Generally speaking, a low temperature environment of 0-10 ° C is preferred. If there is no such condition, room temperature of 15-25 ° C is also acceptable. However, it must be protected from direct sunlight, and the energy in sunlight may cause photochemical reactions.
In addition, it has certain volatility and irritation, and should be sealed for storage. Choose a suitable container, such as a glass bottle, and seal it with a rubber plug or a polytetrafluoroethylene plug to prevent volatilization from escaping, and it can avoid excessive contact with air and prevent oxidation.
In storage, it should also be separated from oxidants, acids, bases and other substances. Due to its active chemical properties, contact with the above substances, or a violent reaction, can cause danger.
In summary, 1-methyl-2-imidazole formaldehyde should be stored in a dry, cool, sealed place, and isolated from incompatible substances, so as to maintain its quality and characteristics for a long time.
