4-(2-chloroethyl)-1H-imidazole hydrochloride (1:1)

The chemical structure of 4- (2-chloroethyl) -1H-imidazole hydrochloride (1:1) is as follows. This compound, based on imidazole, is a five-membered heterocyclic compound containing a dinitrogen atom and is aromatic. At the 4th position of 1H-imidazole, followed by 2-chloroethyl. The so-called 2-chloroethyl group is one of the hydrogen atoms of the ethyl group replaced by the chlorine atom, and the ethyl group is ethane to remove the remaining group of a hydrogen atom. On the basis of this structure, it is complex with hydrochloric acid to form a salt in a ratio of 1:1. The reason for salt formation is that the nitrogen atom on the imidazole ring has a lone pair of electrons, which can form a coordination bond with the hydrogen ion in hydrochloric acid, thus forming the structure of 4- (2-chloroethyl) -1H-imidazole hydrochloride (1:1). In this structure, the presence of chlorine atoms makes the compound have specific chemical activities, which can be used for nucleophilic substitution and other reactions; the imidazole ring also gives it unique chemical properties, which may be important in pharmaceutical chemistry, organic synthesis and other fields.

One of them can be started from imidazole. Imidazole has an active nitrogen atom and can undergo nucleophilic substitution with halogenated hydrocarbons. Mixing imidazole with 2-chloroethanol under appropriate reaction conditions usually requires the presence of a base to facilitate the reaction. The base can capture the hydrogen on the imidazole nitrogen atom, enhance its nucleophilicity, and then replace it with the chlorine atom of 2-chloroethanol to form 4- (2-hydroxyethyl) -1H-imidazole. Subsequently, the product is treated with chlorination reagents such as thionyl chloride to convert the hydroxyl group into a chlorine atom, and finally 4 - (2-chloroethyl) -1H-imidazole is obtained. This intermediate product reacts with hydrochloric acid to obtain 4- (2-chloroethyl) -1H-imidazole hydrochloride (1:1).
Second, other nitrogen-containing heterocyclic derivatives are also used as starting materials. After a series of functional group transformations, the structure of the target molecule is gradually constructed. For example, a nitrogen-containing heterocycle with a specific substituent is first synthesized, and then 2-chloroethyl is introduced through reaction steps such as halogenation and nucleophilic substitution, and finally the target product is obtained as a salt.
Or use the method of catalytic synthesis. Selecting suitable catalysts, such as metal catalysts or organic small molecule catalysts, can improve the selectivity and efficiency of the reaction. Under certain catalytic systems, the reaction can be carried out under milder conditions, reducing the occurrence of side reactions and improving the purity and yield of the product.

Today I have a question, what is the price of 4- (2-chloroethyl) -1H-imidazole hydrochloride (1:1) in the market. This is a compound in the field of fine chemicals, and its price range often varies depending on factors such as quality, supply and demand, origin and supplier.
In the chemical raw material trading market, if the quality is average, the bulk purchase volume is quite large, and the price per kilogram may be around 100 yuan. However, if the quality is high, it is used in special fields such as high-end pharmaceutical research and development, and the purchase volume is small, the price per gram may reach tens of yuan.
For ordinary industrial grade, due to mature production technology, abundant output, and intense market competition, the price becomes more affordable. The pharmaceutical grade has strict requirements on purity, impurity content, etc., and the production is difficult and the cost is high, so the price is high.
Also, the price varies depending on the origin. If it is produced in a place with a mature industrial chain and good cost control, the price may be slightly lower; if it is produced in a remote place with high production costs, the price may be higher.
Furthermore, the different suppliers also affect their prices. Large suppliers may have competitive prices due to scale effects; small suppliers may have slightly higher prices due to operating costs and other reasons. The price of 4- (2-chloroethyl) -1H-imidazole hydrochloride (1:1) is roughly in the range of a few dollars per gram to several hundred dollars per kilogram.
