To prepare 7- (4-hydroxyethyl) -3,4-dihydrofuran-2 (1H) -one, the method is as follows:
First take an appropriate amount of starting material, according to its chemical properties, or can first cause condensation reaction of those containing specific functional groups. In a suitable reaction vessel, add corresponding reagents and catalysts to control the reaction conditions such as temperature and pressure. Temperature regulation is very critical. If the temperature is too high, or side reactions increase, the product is impure; if the temperature is too low, the reaction rate will be slow and take a long time.
During the reaction process, the reaction process needs to be closely monitored. TLC and other means can be used to clarify the degree of reaction progress. When the reaction reaches the expected stage, the post-treatment operation is carried out. Or by extraction, the product is separated from the impurities in the reaction system, and a suitable extractant is selected to ensure that the product can be effectively transferred to the organic phase. Subsequently, the water and insoluble impurities in the organic phase are removed through drying and filtration.
Then perform purification operations such as distillation or column chromatography to obtain high-purity 7- (4-hydroxyethyl) -3,4-dihydrofuran-2 (1H) -one products. When column chromatography, it is crucial to select the right stationary phase and mobile phase, so that the product can be well separated from other impurities.
The whole synthesis process requires fine operation by the experimenter and strict control of each link before the target product can be obtained.

The physical properties of 7- (4-hydroxyethyl) -3,4-diacetyl-2 (1H) -pyrrole are as follows:
This substance is often in solid form, due to the presence of specific atomic connections and groups in its molecular structure, resulting in a specific pattern of intermolecular forces, which in turn tend to form solids.
In terms of melting point, given the energy level of intermolecular interactions, during heating, when a specific temperature is reached, the molecule obtains enough energy to break free from the lattice binding, and the melting point is within a certain range. However, the exact value will vary depending on the purity of the sample and the measurement conditions. The boiling point of
depends on the energy required for the molecule to overcome the intermolecular forces and convert it into a gaseous state. Due to the interaction of hydrogen bonds and van der Waals forces between molecules, the boiling point of the substance is relatively high and is in a specific temperature range.
In terms of solubility, because its molecular structure contains polar groups, it has a certain solubility in polar solvents such as water, but due to the existence of the hydrophobic part of the whole molecule, the solubility is not infinite. In organic solvents such as ethanol and acetone, the solubility may be relatively good. This is based on the principle of similarity and miscibility, and the degree of matching between polar and non-polar parts and organic solvents is determined.
The density is determined by its molecular weight and the degree of molecular packing compactness. Under certain conditions, it has a specific value, reflecting the mass of the substance per unit volume.
In appearance, the pure state may appear white or slightly colored solid, and the specific color may change due to impurities or subtle differences in crystal structure.
These physical properties are important for understanding the behavior of the substance in different environments, the conditions under which it participates in chemical reactions, and practical application scenarios.

7- (4-hydroxyethyl) -3,4-dioxacyclopentene-2 (1H) -one, this is an organic compound. Its chemical properties are quite rich, try to describe it in detail.
This compound contains special functional groups, hydroxyl groups, ether bonds and ketone carbonyl groups, giving it unique reactivity. Hydroxyl groups are nucleophilic and can participate in esterification reactions, co-heat with organic acids, and form corresponding esters. This process is like building a new structural bridge on the organic stage. And hydroxyl groups can be oxidized. Under mild oxidation conditions, they may be converted into aldehyde groups or carboxyl groups. If treated with specific oxidants, the structure will evolve accordingly.
The ether bond is relatively stable in nature, but it will also break under harsh conditions such as strong acid. Just like the strong door is opened under a strong external force, after the ether bond is broken, the compound structure will be recombined and other products will be derived.
Keto carbonyl is the focus of the reactivity of this compound. Carbon in carbonyl is electrophilic and vulnerable to attack by nucleophiles. In Grignard's reagent, carbon negative ions in Grignard's reagent will add to carbonyl carbon to build new carbon-carbon bonds, which will add to organic synthesis.

Looking at what you said, I seem to be asking "the price range of 7- (4-hydroxyethyl) -3,4-dihydroxybenzaldehyde-2 (1H) -quinoline in the market". However, the price of this chemical product varies greatly depending on the quality, source, supply and demand.
In the city, if it is a product of ordinary purity, or due to the production process and raw material cost, the price per gram may be between tens and hundreds of dollars. If high purity is required, due to the difficulty of purification and the complexity of the process, the price may rise sharply, reaching thousands of dollars per gram, or even higher. < Br >
And if there is a large demand for this product and the supply is limited, its price will also increase. On the contrary, if the supply exceeds the demand, the price may be lowered. And in different places, prices vary, which will also cause price fluctuations. To know the exact price, ask chemical raw material suppliers and reagent suppliers for their quotations in detail to get a more accurate price range.
