4(5)-IMIDAZOLECARBOXALDEHYDE HYDROCHLORIDE

4 - (2 - (5 -) imidazole formaldehyde hydrochloride, its physical properties are as follows. This is a white to off-white crystalline powder. In terms of texture, it is fine and pure in color. Its melting point is quite critical, about a certain range, this property is quite significant in identification and purification. Solubility is also an important physical property. In common organic solvents, such as water and ethanol, it exhibits a specific dissolution behavior. In water, depending on the water temperature and the ratio of solute to solvent, it may be partially dissolved or completely dissolved. In ethanol, its dissolution properties are also different, which can provide basis for subsequent preparations and chemical reactions. In addition, its density is also a physical characterization. Although the value is not directly observable, in specific experiments and industrial production processes, the density parameter is crucial for the material ratio and the construction of the reaction system. And its stability is acceptable at room temperature and pressure. In case of high temperature, high humidity or specific chemical environment, or the possibility of changes in properties, this is also an indispensable point when considering its physical properties.

The chemical synthesis method of Fu 4- (2- (5-imidazolyl)) -imidazole formaldehyde hydrochloride, although the ancient book "Tiangong Kaiwu" does not directly describe this substance, it may be useful for chemical synthesis.
The synthesis of ancient times is mostly based on the properties of the substance, and it can be changed by the usual method. To obtain this compound, one can be started from imidazole derivatives. First, the appropriate imidazole is used, and the appropriate substituent is introduced under specific reaction conditions. For example, a halogenated hydrocarbon reacts with it, and under the catalysis of a base, the imidazole substituent is generated. In this step, the reaction temperature, time and the ratio of the reactants should be carefully observed to ensure that the reaction is moderate and impurities are not generated. < Br >
Second, the obtained substituted imidazole is converted into an aldehyde group through oxidation and other steps. In the past, oxidation, or using a mild oxidizing agent, such as a weak oxidizing agent in a moderate environment, oxidizes the specific group to an aldehyde. This process also needs to be carefully regulated. The aldehyde group is easy to reoxidize, and it should be stopped when appropriate.
Third, after the aldehyde group is generated, it interacts with hydrochloric acid to form a hydrochloride salt. In this step, the amount of hydrochloric acid and the reaction environment should be controlled to ensure complete and stable salt formation.
Furthermore, the way of synthesis is also related to the choice of solvent. Although there are no modern solvents in ancient times, it is known that different reactions require suitable solvents to facilitate the progress of the reaction. For example, some reactions require polar solvents to assist the migration and reaction of ions; some require non-polar solvents to dissolve and stabilize the reactants.
Although the synthesis of this compound is not detailed in "Tiangong Kaiji", it can be used as a reference for the synthesis of 4- (2- (5-imidazolyl)) -imidazole formaldehyde hydrochloride. According to this principle, it should be able to be synthesized in the process of synthesis.

4- (2,5-dimethyl-1H-imidazole-1-yl) benzaldehyde hydrochloride, which is useful in many fields such as medicine and chemical industry.
In the field of medicine, it is often the key intermediate for the synthesis of specific drugs. The structure of Gainimidazole and benzaldehyde endows the compound with unique physiological activities. Taking the development of anti-cancer drugs as an example, researchers can modify the structure of the compound to enhance its affinity with specific targets of cancer cells, achieve precise attack on cancer cells, and reduce damage to normal cells, achieving high-efficiency and low-toxicity therapeutic effects. For example, in the development of antibacterial drugs, its structural characteristics can effectively interfere with the metabolic process of bacteria, inhibit the growth and reproduction of bacteria, and add new options for antibacterial drugs. < Br >
In the chemical industry, it plays an important role in the preparation of organic synthetic materials. Because of its reactive group in the structure, it can be used as a crosslinking agent for polymerization reaction, so that the polymer forms a three-dimensional network structure and improves the mechanical properties and stability of the material. For example, in the preparation of high-performance engineering plastics, adding an appropriate amount of this compound can optimize the heat resistance, wear resistance and chemical corrosion resistance of plastics, and is widely used in the manufacture of automotive and aerospace components. At the same time, in the field of dye synthesis, its special structure can provide chromogenic groups for dye molecules, improve the color brightness, light resistance and washing resistance of dyes, and is used in textile printing and dyeing and ink manufacturing industries.

I think what you are asking is about the market price of "4- (2- (5-imidazolyl) -formaldehyde hydrochloride". However, the market price of this chemical substance fluctuates irregularly and is influenced by many factors.
First, the price of raw materials. If the price of all the raw materials required for the synthesis of this substance rises and falls, the price of the finished product will also change accordingly. Second, if there is a new technique that greatly increases the production efficiency and reduces the cost, the price may be lowered; conversely, if there is a stagnation in the technique, the cost will rise and the price will also rise. Third, the trend of supply and demand, if the market demand for this product is strong, but the supply is limited, the price will be higher; if the demand is weak and the supply is excessive, the price will be lower.
And due to the differences in market regions, prices, taxes, and transportation fees vary from place to place, resulting in different prices. And different merchants have different pricing due to different business strategies and cost control.
Therefore, it is difficult to know the exact market price in a word. It is necessary to check the chemical product trading platform in detail and consult relevant chemical distributors or manufacturers in order to get a more accurate price.

4- (2- (5-imidazolyl)) -imidazolyl formaldehyde hydrochloride, the way to hide it is related to its nature and quality. This material is delicate and should be stored in a cool and dry place, avoiding heat and humidity. If exposed to heat, it is afraid of its transformation and loss of its original effect; if it is in a wet environment, it is easy to deliquescence and damage its shape.
The utensils hidden should also be paid attention to. When using glass or porcelain utensils, because they do not react with the object, they can keep their purity. And the utensils must be sealed to prevent the entry of air and water vapor to prevent oxidation and deliquescence.
Also, the light of the hiding place should be dark rather than bright. Under strong light, it may be induced by its photochemical reaction, causing a qualitative change. Therefore, it is appropriate to place it in a dark room, or hide it with a light-shielding device. In this way, it can have all its quality and preserve its character for later use. If you hide it properly, this thing can be used for a long time, and it is helpful for all kinds of uses.
