6,7-Diethoxy-1- (3,4-diethoxy-phenyl) -3,4-dihydroisoquinoline benzoate is one of the organic compounds. Its physical properties are particularly important, and it is related to many uses and characteristics of this compound.
This compound may be in a solid state at room temperature. Looking at its appearance, it may be a white to off-white powder, fine and uniform, and its quality is relatively stable. This is due to the intermolecular force, which makes the molecules arranged in an orderly manner to form a solid structure.
The melting point is about a specific temperature range. The melting point is the critical temperature at which a substance changes from a solid state to a liquid state. The specific value of the melting point of the compound is determined by its molecular structure. The force of chemical bonds between atoms and intermolecular interactions, such as van der Waals force and hydrogen bond, all affect the melting point. In its molecular structure, groups such as ethoxy and phenyl interact to build a specific lattice energy, thus determining the melting point.
In terms of solubility, it may exhibit certain solubility in common organic solvents. In polar organic solvents, such as ethanol and acetone, there may be moderate solubility. This is because polar solvents and compound molecules can form hydrogen bonds, dipole-dipole interactions, etc., to help the compound molecules disperse in the solvent. However, in non-polar solvents, such as n-hexane, the degree of solubility may be limited. The polarity difference between edge non-polar solvents and compounds is large, and the intermolecular force is weak, making it difficult to overcome the attractive force between molecules of compounds.
Density is also one of its physical properties. Density reflects the mass per unit volume of a substance and is related to the compactness of the compound molecules. The compactness of its molecular structure, the type and number of atoms, are all left and right density values.
In addition, the compound may have a specific refractive index. Refractive index is a measure of the change in direction when light propagates in a substance, and is related to the polarizability of the substance molecules. The distribution of electron clouds and the properties of chemical bonds in compounds all affect the refractive index.
In summary, the physical properties of 6,7-diethoxy-1 - (3,4-diethoxy phenyl) -3,4-dihydroisoquinoline benzoate, such as appearance, melting point, solubility, density, and refractive index, are determined by its unique molecular structure, and these properties play a key role in its applications in chemistry, medicine, and other fields.

I think you are asking about the market price of 6,7-diethoxy-1 - (3,4-diethoxybenzoyl) -3,4-dihydroisoquinoline formate. However, this product is not a common product in the market, and its price often varies due to many factors, which is difficult to determine.
First, the price fluctuation of raw materials has a great impact. If the price of the raw materials required for the synthesis of this compound fluctuates due to origin, season, supply and demand, etc., the price of the finished product will also change accordingly. Second, the difficulty and cost of preparation are also key. The structure of this compound is slightly complicated. If the synthesis process is cumbersome, special reagents and equipment are required, or the reaction conditions are strict, the cost will be high, and the price will be high. Third, the amount of market demand affects its price. If many pharmaceutical companies and scientific research institutions have strong demand for this substance, but limited supply, the price will rise; on the contrary, if the demand is low, the price may decline.
And the market conditions in different places are different, and different merchants have their own pricing considerations. Or due to different transportation costs and business strategies, the price difference. Therefore, in order to know the exact market price, it is necessary to carefully investigate the chemical raw material market, consult relevant suppliers, or refer to the price of congeneric products, and comprehensively compare, in order to obtain a more accurate number. However, it is difficult for me to tell you the exact price at this time.
