2 - (2 - hydroxyethyl) thiophene is an organic compound with specific physical properties. It is colorless to pale yellow liquid and exists stably at room temperature and pressure.
Looking at its properties, it is a liquid at room temperature, which is caused by the intermolecular forces and structures. The molecule contains thiophene ring and hydroxyethyl group, which endows it with a certain polarity, which affects the interaction between molecules and makes the substance appear liquid. The boiling point and melting point of
2 - (2 - hydroxethyl) thiophene are also important physical properties. The boiling point is related to the energy required for the molecule to break free from the liquid phase binding. The boiling point of this compound is determined by the synergistic effect of various groups in the molecular structure; the melting point reflects the critical temperature from the solid state to the liquid state, which is determined by the lattice energy and the intermolecular forces.
Furthermore, the solubility is also critical. Because it contains polar hydroxyethyl, it has a certain solubility in polar solvents such as ethanol and water. However, the non-polarity of the thiophene ring limits its solubility in water, resulting in its non-excellent solubility in water, but it can be better dissolved in some organic solvents, providing convenience for chemical synthesis and separation.

2-%282+-+Hydroxyethyl%29thiophene is 2 - (2 - hydroxyethyl) thiophene, which has unique chemical properties. It has certain stability, but under certain conditions, it also shows active reactivity.
Looking at its structure, the thiophene ring is an aromatic system, endowing it with certain electron delocalization characteristics, which makes the overall structure relatively stable. The electron cloud distribution of the thiophene ring affects its reactivity, and the electrophilic substitution reaction is more likely to occur at a specific position on the thiophene ring.
The 2 - hydroxyethyl group of the side chain contains the active functional group hydroxyl. Hydroxyl is nucleophilic and can participate in many reactions. In case of active halogenated hydrocarbons, a nucleophilic substitution reaction can occur. The oxygen atom of the hydroxyl group attacks the carbon atom of the halogenated hydrocarbon, and the halogen atom leaves to form ether derivatives.
In an acidic environment, the hydroxyl group can be protonated, enhancing its ability to leave, promoting the elimination reaction within or between molecules to form compounds containing double bonds. At the same time, the hydroxyl group can participate in the esterification reaction, and dehydrate with organic acids or their derivatives under the action of catalysts to form ester bonds.
In addition, 2- (2-hydroxyethyl) thiophene contains sulfur atoms, and sulfur atoms have lone pairs of electrons, which can participate in the reaction as electron donors, affecting the electron cloud density and reactivity of molecules. This compound is rich in chemical properties and can be used as a key intermediate in the field of organic synthesis. It can construct multiple organic compound structures through different reaction paths.

To prepare 2 - (2 - hydroxyethyl) thiophene, there are many methods, each with its own advantages and disadvantages, which are described in detail below.
First, thiophene is used as the starting material and can be obtained by reacting with ethylene oxide. This reaction needs to be carried out in the presence of suitable catalysts. Commonly used catalysts include Lewis acids, such as aluminum trichloride. Thiophene has an electron-rich aromatic system, while ethylene oxide is an active epoxy compound. Under the action of the catalyst, the electron cloud density of the β-position of thiophene is high, and it is vulnerable to nucleophilic attack of ethylene oxide. After ring opening, 2 - (2 - hydroxyethyl) thiophene is rearranged to form 2 - (2 - hydroxyethyl) thiophene. The advantage is that the raw materials are relatively easy to obtain and the reaction route is relatively direct. However, the disadvantages are also obvious. The reaction conditions may be harsh, and the reaction temperature and catalyst dosage need to be precisely controlled. Otherwise, side reactions are easy to occur and the yield is not high.
Second, the hydroxyl group of 2-thiophene ethanol is prepared by specific protection and deprotection strategies. First, the hydroxyl group of 2-thiophene ethanol is protected with a suitable protective group, such as a silicon ether protective group. The protected compound can be modified through a series of reactions, and finally the protective group is removed to obtain the target product. The advantage of this strategy is that it can effectively protect the hydroxyl group, avoid unnecessary side reactions during the reaction process, and improve the selectivity of the reaction; however, the process is slightly complicated and requires multiple steps, which increases the preparation cost and time, and the introduction and removal steps of the protective group also require fine operation to ensure the purity and yield of the product.
Third, the synthesis path involving organometallic reagents is used. For example, lithium thiophene reagent reacts with 2-halogenated ethanol derivatives. The lithium thiophene reagent can be prepared by the reaction of thiophene and butyl lithium and other strong bases. It has strong nucleophilic properties and can react with the halogen atom of 2-halogenated ethanol derivatives to generate 2- (2-hydroxyethyl) thiophene. The advantage of this method is that the reactivity is high and can be carried out under relatively mild conditions; however, the organometallic reagents are mostly highly active and have strict requirements on the reaction environment. They need to be operated under anhydrous and anaerobic conditions, which increases the difficulty and cost of the experiment.

Today there is a question about the price range of 2 - (2 - hydroxyethyl) thiophene in the market. This substance is an important raw material for organic synthesis and is widely used in medicine, pesticides, materials and other fields.
However, its price is not static, and it often fluctuates due to multiple reasons. First, it is affected by the cost of raw materials. If the price of the basic raw materials required for the synthesis of 2 - (2 - hydroxyethyl) thiophene rises, its cost will also increase, and the price will rise as the tide rises. Second, the market supply and demand relationship determines its price. If the market has strong demand for it and limited supply, the price will rise; conversely, if the supply exceeds the demand, the price may fall. Third, production processes and technologies also play a role. Advanced technology can reduce costs and increase output, which in turn affects prices.
According to the current market conditions, the price of 2 - (2-hydroxyethyl) thiophene is about a few hundred to several thousand yuan per kilogram. For ordinary purity, it is several hundred yuan per kilogram or several hundred yuan; however, if the purity is extremely high and reaches special standards such as pharmaceutical grade, the price may soar to several thousand yuan per kilogram. However, this is only a general range, and the actual price depends on factors such as the time and place of the specific transaction, the number of transactions, and the negotiation between the buyer and the seller. For the exact price, you need to consult the relevant chemical product suppliers or market practitioners.
