First look at its main body, isosclic anhydride is the key structural part. The isosclic anhydride has a unique five-membered ring structure with two carbonyl groups in the ring, which gives the compound specific reactivity and chemical properties.
Then look at the substituent, 3,4-dimethoxybenzyl, benzyl is benzyl, and methoxy is substituted at the 3rd and 4th positions of the benzene ring. Methoxy group is the power supply group, which can affect the electron cloud density of the phenyl ring, which in turn affects the overall chemical activity and physical properties of the benzyl group after being connected to the host isosclic anhydride.
There are 6,7-dimethoxy groups, which have methoxy substitutions at the 6 and 7 positions of the isosclic anhydride ring. These methoxy groups also affect the electron cloud distribution of the isosclic anhydride ring, changing the polarity, solubility and reaction check point selectivity of the compound.
Overall, the chemical structure of (3,4-dimethoxy benzyl) -6,7-dimethoxy isosclic anhydride (1:1) is composed of isosclic anhydride rings with specific activities, which are cleverly connected with multiple methoxy-containing substituents. This unique structure makes it potentially valuable in the fields of organic synthesis, medicinal chemistry, etc. Because of its diverse reaction check points and electronic properties, it can participate in a variety of chemical reactions, providing the possibility for the preparation of special functional compounds.

To prepare 1- (3,4-dimethoxybenzyl) -6,7-dimethoxyisocoumarin (1:1), there are various methods.
First, the corresponding phenols can be started. First, the phenol is etherified to introduce a methoxy group to obtain a phenol ether containing a specific substituent. Then, the acylation reaction is used to connect the acyl group at the appropriate check point of the phenol ether to form a key intermediate. Then, the coumarin mother core is constructed through the step of intramolecular cyclization. During the process, attention is paid to the control of reaction conditions, such as temperature, catalyst type and dosage, in order to promote the smooth progress of the reaction and improve the yield of the target product. < Br >
Second, benzene ring derivatives can also be used as starting materials. After multi-step reactions, dimethoxy substitutions are built in sequence, and functional groups that can participate in the cyclization reaction are ingeniously introduced. The molecular structure can be gradually constructed by a series of reactions such as nucleophilic substitution, oxidation, and condensation. During each step of the reaction, the product needs to be carefully separated and purified to remove impurities and ensure that the reaction advances in the expected direction.
Third, semi-synthesis using natural products as raw materials can be considered. Find natural coumarins with similar structures, and convert them into the target 1- (3,4-dimethoxybenzyl) -6,7-dimethoxyisocoumarin by means of chemical modification, such as substituent transformation and structural modification. This approach may take advantage of the inherent structural advantages of natural products to simplify some synthesis steps, but it is necessary to study the source, extraction and modification reaction of natural products in detail.
All synthesis methods have advantages and disadvantages, and they need to be selected according to many factors such as the availability of raw materials, the ease of control of reaction conditions, and the purity and yield of the product.

1 - (3,4 -dimethoxybenzyl) -6,7 -dimethoxyisoflavone anhydride (1:1) The physical and chemical properties of this substance are as follows:
In appearance, it is often in the state of powder or crystalline solid. The powder texture is fine, and the crystallization may have a regular geometric shape. The specific appearance may vary depending on the preparation method and purity.
In terms of solubility, it has a certain solubility in organic solvents such as ethanol, chloroform, dichloromethane, etc. Due to the presence of groups such as methoxy groups in the molecule, it can form an appropriate intermolecular force with the organic solvent, which is conducive to dissolution. However, the solubility in water is poor, because the whole molecule is relatively hydrophobic, it is difficult to form an effective interaction with water. In terms of stability,
is relatively stable under normal conditions. However, in the case of strong acid and alkali, the acid anhydride part of the molecular structure is easy to hydrolyze, resulting in structural changes. And high temperature environment may also affect its stability, or trigger decomposition reactions.
Melting point and boiling point, the melting point is about [specific value] ° C. At this temperature, the substance changes from solid to liquid. The boiling point is difficult to determine precisely because the substance has decomposed before reaching the boiling point.
Spectral properties, in the infrared spectrum, there are characteristic absorption peaks at specific wavenumbers. For example, the C = O stretching vibration absorption peak of the acid anhydride is in the 1800-1750 cm < unk > and 1790-1740 cm < unk > region, which can help identify the acid anhydride structure. In H-NMR spectroscopy, hydrogen atoms in different chemical environments correspond to different chemical shifts, which can provide information such as the location and number of hydrogen atoms in molecules, which is an important basis for structure confirmation.

I think what you are asking is about (3,4-dimethylhydroxybenzyl) -6,7-dimethylhydroxyisoanhydride (1:1) in the market price range. However, the chemicals involved are quite professional, and as far as I know, it is difficult to know the exact price immediately.
The price of such chemicals is often affected by many factors. First, the ease of preparation. If the preparation process is complicated and special raw materials and processes are required, the cost will be high and the price will rise accordingly. Second, the market supply and demand situation. If there are many people who want it, and the supply is scarce, the price will rise; conversely, if the supply exceeds the demand, the price may be reduced. Third, the difference between manufacturers and brands will also lead to price differences. Famous factories produce products, or due to strict quality control and good reputation, the price is slightly higher.
To know the exact price range, you can go to the chemical trading market for details, or consult the relevant chemical product price information platform, or contact the relevant manufacturers and distributors to get a more accurate price range. Although I can't give you the price directly, I hope this advice can help you find what you need.
