In the field of medicine, it can be used as a pharmaceutical intermediate to help synthesize drugs with specific physiological activities, such as some antibacterial and antiviral drugs. With its unique chemical structure, it gives better efficacy and safety to drugs. In the field of materials science, it can be used to prepare functional materials, such as materials with special adsorption and separation properties. Because of its structural characteristics, it can selectively adsorb or separate specific substances, and play a role in the purification of chemical products and the treatment of environmental pollutants. In the field of organic synthesis, it is often used as a key raw material or catalyst to promote various organic reactions, because it can change the reaction path, reduce the activation energy of the reaction, improve the efficiency and selectivity of the reaction, and assist in the synthesis of complex organic compounds. In biochemical research, it is sometimes used for biomolecular markers or probe design.

2-%282+-+Hydroxyethyl%29benzimidazole is 2 - (2 - hydroxyethyl) benzimidazole, and its synthesis method is as follows:
The starting materials are mostly o-phenylenediamine and glycolic acid. In the reaction kettle, add an appropriate amount of o-phenylenediamine, dissolve it with an appropriate amount of organic solvents such as ethanol and toluene, and stir well. Add glycolic acid dropwise, and pay attention to the system changes during the process. Add it dropwise and slowly heat up. Generally speaking, the temperature rises to 120-150 ° C, which is a key step. Temperature control is related to the reaction process and product purity. Maintain this temperature, the number of reactions, and the specific duration are determined according to the reaction monitoring. Commonly used TLC (thin layer chromatography) monitoring, when the raw material point almost disappears and the product point is clear, the reaction < Br >
After the reaction is completed, wait for the system to cool down. The cooling method also needs to be considered. If it is cooled too fast or causes the crystals to be fine, too slow will affect the efficiency. After cooling, extract with an appropriate solvent such as ethyl acetate, dichloromethane, etc. The extraction process is repeated many times to fully extract the product. The extracts are combined and dried with anhydrous sodium sulfate to remove the moisture. After drying, the organic solvent is distilled under reduced pressure to obtain a crude product.
The crude product still needs to be purified. Usually column chromatography is used to fix the phase and select silica gel, and the mobile phase is prepared according to the characteristics of the product. For example, petroleum ether and ethyl acetate are mixed in a specific ratio. Pure 2 - (2 -hydroxyethyl) benzimidazole can be obtained by column chromatography, the fraction containing pure product is collected, and the mobile phase is removed by rotary evaporation.
There are also those who use o-nitroaniline as the starting material. First, o-nitroaniline is reduced to o-phenylenediamine. Common reduction methods include iron powder reduction and catalytic hydrogenation. After obtaining o-phenylenediamine, the subsequent steps are similar to those started with o-phenylenediamine above. After reaction with glycolic acid, post-treatment and purification, the target product is also obtained.
During the synthesis process, many factors affect the yield and purity of the product. Temperature, reaction time, raw material ratio, solvent type, etc. all need fine regulation. If the temperature is too high, or cause more side reactions; if the time is too short, the reaction is incomplete. Improper ratio of raw materials also affects the formation of products. Therefore, during synthesis, it is necessary to repeatedly explore and optimize the reaction conditions to obtain satisfactory results.

2 - (2 -hydroxyethyl) benzimidazole is one of the organic compounds. Its physical and chemical properties are quite specific, and it has important uses in many fields.
Let's talk about its physical properties first. This substance is mostly solid under normal conditions, and its color may be white to light yellow powder, and its texture is fine. The melting point is relatively high, which makes it melt at a specific temperature environment, providing the possibility for its application under high temperature conditions. And its solubility is also worthy of attention. In some organic solvents, such as ethanol, dichloromethane, etc., it can have a certain solubility, but its solubility in water is relatively limited. This difference in solubility makes it different in the reaction and separation of different solvent systems.
As for chemical properties, 2 - (2 - hydroxyethyl) benzimidazole molecules contain benzimidazole rings and hydroxyethyl functional groups. The benzimidazole ring has certain aromaticity and stability, which endows the molecule with certain chemical inertness. However, the nitrogen atom on the ring can be used as an electron donor to participate in the coordination chemical process and form a stable complex with metal ions. This property is very useful in the fields of catalysis and materials science. The existence of hydroxyethyl functional groups adds molecular hydrophilicity, and the hydroxyl group can undergo many reactions such as esterification and etherification, providing various paths for its chemical modification and derivatization. Because it contains both hydrophilic groups and aromatic structures, it can be chemically modified to play a unique role in surfactants and drug synthesis.

Today, I have inquired about the price of 2 - (2 - hydroxyethyl) benzimidazole in the market. However, the market is volatile and varies from place to place, so it is difficult to determine its price.
I have heard of "Tiangong Kaiwu", which describes the production system of various things, but it does not involve the price of this thing. If you want to know the price of this thing, you should visit the market in detail.
Or you can ask pharmaceutical companies, covering the field of this thing or medicine; or you can ask chemical companies, because it can also be a raw material for chemical industry. If you are in a place where business is concentrated, you can get a rough price. < Br >
Generally speaking, the range of its price is difficult to determine. Or the price varies depending on the quality and quantity. And the supply and demand of the city is also the reason. If there are many applicants and few suppliers, the price will rise; on the contrary, if the supply exceeds the demand, the price will be depressed.
Therefore, if you want to know the confirmed price of 2 - (2 - hydroxyethyl) benzimidazole in the market, you can only get it when you go to the city in person and consult widely.

2-%282+-+Hydroxyethyl%29benzimidazole is 2 - (2 - hydroxyethyl) benzimidazole. Many things need to be paid attention to during the use of this substance.
First, it is related to safety protection. Because it has certain chemical activity, appropriate protective equipment must be worn during operation. If wearing protective gloves, avoid direct contact with the skin to prevent it from irritating the skin and may even cause adverse reactions such as allergies. Also wear goggles to prevent this substance from accidentally splashing into the eyes and causing damage to the eyes. At the same time, ensure that the operating environment is well ventilated. If inhaling its volatiles, it may irritate the respiratory tract and endanger health.
Second, pay attention to storage conditions. Store in a dry, cool and ventilated place, away from fire and heat sources. Due to its chemical properties, high temperature environment may increase its chemical reactivity, or reduce its stability, or even decompose. And it is necessary to avoid mixing with oxidizing agents, acids and other substances to prevent dangerous chemical reactions.
Third, the operating specifications are also crucial. Before use, it is necessary to fully understand its chemical properties and reaction characteristics, and strictly follow the operating procedures. When weighing, it is necessary to operate accurately to ensure the accuracy of the dosage, so as to avoid affecting the experimental or production results due to improper dosage. When conducting relevant chemical reactions, it is necessary to closely monitor the reaction conditions, such as temperature, reaction time, pH, etc. Because the reactivity is significantly affected by these factors, there is a slight deviation, or the reaction cannot meet expectations, and even generates by-products, which affects the quality of the product.
