In the field of materials science, it may also be used as an important component in the preparation of materials with special properties. By participating in polymerization reactions, etc., the material is endowed with unique electrical, optical or mechanical properties. For example, in the preparation of some organic optoelectronic materials, the introduction of this structural unit may optimize the charge transport performance and luminous efficiency of the material, and contribute to the development of new display technologies and optoelectronic devices.
Furthermore, it is also a key intermediate in the total synthesis of natural products. For many natural products with complex structures, the synthesis process often relies on this structure as a basic module, gradually splicing and modifying, and finally reproducing the complex structure of natural products, and exploring their biological activities and pharmacological mechanisms.

To prepare 1- (3,4-dihydroxybenzoyl) -6,7-dihydroxy-3,4-dihydroisoflavone, the synthesis method is as follows:
First, flavonoids are used as starting materials. Flavonoids containing appropriate substituents can be obtained first, and their structures can be modified under specific reaction conditions. In a suitable solvent, suitable reagents are added to adjust the reaction temperature and time to gradually transform the structure of flavonoids. For example, by using some nucleophilic reagents, substitution reactions occur with flavonoids at specific positions, and required bishydroxybenzoyl groups and dihydroxy groups are introduced. After multi-step reactions, the structure of the target product is achieved.
Second, starting from simple phenolic compounds. Select phenolic substances containing hydroxyl groups, through the activity of phenolic hydroxyl groups, and the corresponding acylating reagents under the action of catalysts, acylation reactions occur to construct a preliminary structural framework. Then use the methods of condensation reaction and cyclization commonly used in organic synthesis to gradually form the parent nuclear structure of isoflavones, and introduce the second hydroxyl group and other substituents at specific positions in appropriate steps. This process requires fine regulation of the reaction conditions to ensure that the reaction proceeds in the direction of the target product and avoid unnecessary side reactions.
Third, with the help of the method of natural product transformation. There are some natural products with similar structures in nature, which can be extracted and separated. Then, according to the existing structure of the natural product, some functional groups are selectively modified by means of chemical modification. Through oxidation, reduction, substitution and other reactions, the natural product is gradually converted into 1- (3,4-dihydroxybenzoyl) -6,7-dihydroxy-3,4-dihydroisoflavone. This approach requires in-depth understanding of the source and properties of the natural product, and the reaction steps need to be reasonably designed according to the specific structure of the natural product.

3,4-Dihydroxybenzoyl, 6,7-dihydroxy-3,4-dihydroisocoumarin and other substances have unique physical and chemical properties.
In appearance, it is mostly white to light yellow crystalline powder with fine texture, and the color may change slightly under different environmental conditions. In terms of solubility, it is slightly soluble in water, but easily soluble in organic solvents such as ethanol and acetone. This property makes it exhibit different dispersion states in different solvent systems, which is of great significance in the field of organic synthesis and preparation. < Br >
In terms of stability, it can remain relatively stable in dry and cool environments, but in high temperature and high humidity environments, chemical reactions are prone to occur and the structure may change. For example, in high temperature and aerobic environments, the hydroxyl groups on the benzene ring are easily oxidized, causing their color to deepen and their activity to decrease.
In terms of its chemical activity, its molecular structure contains phenolic hydroxyl groups and lactone rings, which are chemically active. Phenolic hydroxyl groups can undergo esterification and etherification reactions. In organic synthesis, they are often used as reaction check points to construct more complex compounds; lactone rings can undergo ring-opening or ring-closing reactions under acid-base conditions. This property is crucial in the fields of drug synthesis and total synthesis of natural products. It provides a basis for creating new compounds and expanding their application range.
Its spectral properties are also unique. There are specific absorption peaks in the ultraviolet spectrum. By analyzing the position and intensity of the absorption peaks, it can be used for qualitative and quantitative analysis. It provides convenience for component identification and content determination, and plays a significant role in quality control and analysis and detection.

Looking at your question, I am inquiring about the price of 1 - (3,4 - dimethoxy phenyl) - 6,7 - dimethoxy - 3,4 - dihydroisoflavone in the market. However, I am in the context of "Tiangong Kaiwu", and it is difficult for me to know the price of such fine chemical synthesis.
At that time, most of the practices such as agricultural mulberry, hardware, pottery, etc. were important, and there was no such fine organic synthesis. Although I am familiar with the prices of various natural products, such as silk, porcelain, and iron and copper, I have heard of the ups and downs of the market. However, this chemically synthesized product is neither a natural material and chemical product, nor is it made by traditional techniques, so it is beyond my knowledge.
In today's world, science and technology are changing day by day, and the way of chemistry is advancing, so this fine compound can be obtained. The preparation method may require exquisite instruments and complex processes, which are not comparable to our skills. And its use, or in new fields such as medicine and chemical industry, its price depends on the wide range of uses, the difficulty of preparation, and the amount of demand. Although I have the intention to help you, it is difficult to know the price of 1- (3,4-dimethoxyphenyl) -6,7-dimethoxy- 3,4-dihydroisoflavone in today's market.

1 - (3,4 - dimethoxyphenyl) - 6,7 - dimethoxy - 3,4 - dihydroisoquinoline There are many safety precautions. In the context of "Tiangong Kaiwu", it is stated in the text as follows:
When preparing and using this compound, the first thing to pay attention to is the purity of the material. If the raw material contains impurities, the reaction may be biased, the product is impure, or accidental side reactions may occur. For example, "Tiangong Kaiwu" says that "the purity of the material is the beginning of the good work", the purity of the material is the basis for a smooth reaction.
The reaction environment is also crucial. Temperature, humidity, and air pressure all need to be precisely controlled. If the temperature is too high, it may cause the reaction to be too fast, causing danger; if it is too low, the reaction will be slow and time-consuming. Just like "the heat is moderate, the device can be formed". In the preparation of this compound, the temperature is suitable, and the effect can be obtained. The humidity should not be underestimated. The high humidity environment may cause the raw materials and products to deteriorate under moisture.
Furthermore, when operating, it is necessary to strictly abide by the procedures. The use of various instruments should be done in sequence and should not be confused. For example, the operation of the equipment in "Tiangong Kaiwu" has a fixed method, and the related operation of this compound is also the same. There is a slight difference, or it may lead to disaster.
In addition, the waste gas and waste liquid generated by the reaction should not be discarded at will. Waste gas or dirty air, waste liquid or contaminated water and soil. It needs to be handled properly to ensure that the environment is safe. This is the principle of "the aftermath of work is related to heaven and earth".
Personnel protection should not be ignored. When exposed to this compound, use appropriate protective equipment, such as gloves, goggles, etc., to prevent it from coming into contact with the skin and eyes and harming the human body.
In short, the operation of 1- (3,4-dimethoxyphenyl) -6,7-dimethoxyphenyl-3,4-dihydroisoquinoline must be done with caution, and all links should be followed in order to ensure safety and proper preparation.
