(S) -1,2,3,4-tetrahydro-6,7-diethoxy-3-isopropylbenzofuran-5-carboxylic acid methyl ester, which is an organic compound. Its physical properties are as follows:
Looking at its morphology, it is a crystalline solid under normal conditions, with a certain crystal structure, which is due to the orderly arrangement of intermolecular forces. When this compound is in a solid state, the molecules are tightly packed, or its appearance is a crystal with a regular geometric shape, and the crystal surface is smooth and shiny.
When it comes to the melting point, due to the specific molecular structure, it contains polar ethoxy groups and carboxylic acid methyl ester groups, which enhance the intermolecular forces and cause the melting point to be relatively high. The specific value may vary depending on the impurities and the test conditions, but it is roughly in a certain temperature range. When heated to this temperature range, the compound gradually melts from solid to liquid, and the thermal motion of the molecules intensifies, overcoming the lattice energy and disintegrating the lattice structure.
In terms of boiling point, the compound has a relatively large molecular mass and strong intermolecular forces, including van der Waals forces and dipole-dipole interactions. To make it boil, it needs to provide enough energy to overcome the attractive force between molecules, so the boiling point is quite high. When the boiling point is reached, the liquid compound converts to a gaseous state, and the molecules get rid of the liquid phase binding and move freely in space.
In terms of solubility, due to its polar group and non-polar benzene ring structure, it is amphiphilic. In polar organic solvents, such as ethanol and acetone, due to the formation of hydrogen bonds or dipole-dipole interactions between polar groups and solvent molecules, it exhibits good solubility; in non-polar organic solvents, such as n-hexane, non-polar benzene rings have van der Waals forces with solvent molecules, and also have certain solubility, but the solubility may be lower than that of polar solvents.
Density may be related to the degree of molecular packing compactness and relative molecular weight. Due to the compact structure of the molecule, the relative molecular weight is large, and the density may be greater than that of common organic solvents. Compared with water, it contains more hydrophobic groups, or is insoluble in water and has a density greater than that of water, and settles in water.
The compound may have a specific refractive index, which reflects the degree of influence on the direction of light propagation. The refractive index is determined by the molecular structure and electron cloud distribution, and is a physical constant for identifying the compound.

To prepare (S) -1,2,3,4-tetrahydro-6,7-diethoxy-3-isobutylenyl-benzodihydropyran-4-carboxylic acid p-methoxyphenyl ester, the method is as follows:
First take an appropriate amount of starting materials and place them in a clean reactor. The environment in the kettle needs to be maintained at a specific temperature and pressure, and the reaction system must be in an inert gas atmosphere to prevent the oxidation of the raw materials. The proportion of the starting materials taken must be precisely prepared. Due to a slight deviation in the proportion, the reaction results may be very different.
Then slowly add a specific catalyst. This catalyst is the key to the reaction, which can effectively reduce the activation energy of the reaction and accelerate the reaction process. When adding, the speed should be slow, and the stirring should be continued to make the catalyst evenly dispersed in the reaction system.
During the reaction process, it is necessary to closely monitor the various indicators of the reaction. If the temperature changes, it must be adjusted in a timely manner according to the reaction process to maintain the temperature within a suitable range. If the temperature is too high, it may cause side reactions to occur; if the temperature is too low, the reaction rate will be too slow and take a long time.
When the reaction reaches the expected level, the reaction products will be separated and purified. Methods such as column chromatography and recrystallization can be used to remove impurities in it to obtain high-purity (S) -1,2,3,4-tetrahydro-6,7-diethoxy-3-isobutenyl-benzodihydropyran-4-carboxylic acid p-methoxyphenyl ester. The separation and purification process must be carefully operated to avoid product loss or the introduction of new impurities.
After the above steps and careful operation, the desired compound can be successfully prepared.

I look at what you said (S) -1,2,3,4-tetrahydro-6,7-diethoxy-3-isopentenyl flavonol p-methoxyphenylacrylate, which is a rather professional chemical substance. As for its market price, it is difficult to make a sudden conclusion.
Because of the market price pattern, it is subject to many factors. First, the availability and cost of raw materials are the key. If the raw materials are rare, difficult to collect, or difficult to prepare, the cost will be high, and the price will also be high. Second, the complexity of the preparation process also has a big impact. If you need a delicate and complex method, it will consume a lot of manpower and material resources, and the price will also rise. Third, the market supply and demand will determine the price. If there are many people who want it, the price will be raised; on the contrary, if the supply exceeds the demand, the price will be depressed. Fourth, the brand, quality and scale of the manufacturer are also related to the price. Well-known large factories, those with excellent quality, the price may be high; small factories produce, the price may be slightly lower.
At present, I do not know the material raw materials, processes, supply and demand and manufacturers, so it is difficult to determine its market price. For details, you can consult chemical market merchants, industry experts, or consult relevant market survey reports to get a more accurate price.
