Fu 2- (2-hydroxyquinoline-4-yl) -2-methoxybenzyl-methoxycarbamoyl acetic acid, which has a wide range of uses. In the field of medicine, this compound may have unique pharmacological activities. The hydroxyquinoline group contained in the guine structure can often be combined with specific targets in the body, such as the activity check point of some enzymes, or the receptor on the cell surface, so as to play the role of regulating physiological functions. Or it can be used to develop new drugs to treat specific diseases, such as inflammation, tumors, etc. In the treatment of tumors, it may be able to interfere with the growth and proliferation signaling pathways of tumor cells by virtue of its structural properties, so as to achieve the purpose of suppressing tumors.
In the field of materials science, this compound can also be used. Its special structure endows it with certain optical and electrical properties. For example, it can be used as a component of luminescent materials, because of its electronic transition characteristics in molecules, or can emit specific wavelengths of light under specific conditions, and can be used in organic Light Emitting Diodes (OLED) and other optoelectronic devices to improve their luminous efficiency and color purity. And because it contains groups such as methoxy groups, it may affect the solubility and stability of the material, which is helpful for the preparation of functional materials with excellent performance.
In the field of chemical synthesis, this compound is often an important intermediate. Its rich activity check point can further derive compounds with more complex and diverse structures through various chemical reactions, such as substitution reactions, addition reactions, etc., providing a key cornerstone for the development of organic synthetic chemistry and expanding the types and functions of organic compounds.

To prepare AMMA (Z), and 2- (2-hydroxypyrimidine-4-yl) -2-methylhydroxybenzyl-methylhydroxyhydroxyglycolic acid, the method is as follows:
First take an appropriate amount of raw materials, in a clean kettle, at a suitable temperature and pressure, condensation reaction. A specific catalyst can be selected to promote a smooth reaction. The choice of catalyst is related to the rate and yield of the reaction, and it needs to be done with caution.
When condensing, pay close attention to the fluctuation of temperature. If the temperature is too high, or side reactions will occur, the product will be impure; if the temperature is too low, the reaction will be slow and take a long time. < Br >
After the reaction is completed, the preliminary product is obtained by subtle separation techniques. Or use distillation to separate the product from impurities by the difference in boiling points of different substances; or use extraction to purify the product according to the solubility of the substance in different solvents.
Then, the preliminary product is refined. Or recrystallize, choose an appropriate solvent, dissolve the product in it, and then cool and crystallize to remove other impurities to obtain a high-purity product.
There are other ways to prepare it. Or change the order of the reaction, first modify some groups, and then perform condensation and other reactions. However, no matter what method is used, it is necessary to repeatedly test and observe the influence of various reaction conditions in order to obtain the best method, increase the quality and quantity of the product, and comply with the principles of green and high efficiency, which is feasible in actual production.

The following are the physical and chemical properties of this compound:
This compound contains specific groups. In terms of physical properties, it is difficult to form an effective interaction with water molecules at room temperature or in a solid state. Due to the interaction between the groups, the molecular arrangement is relatively regular and orderly, resulting in a certain degree of crystallinity. Looking at its appearance, it may be a white crystal with a shiny surface and a relatively brittle texture.
When it comes to solubility, in polar solvents, such as water, the solubility is poor or poor. Due to the hydrophobic properties of the internal molecular groups, it is difficult to form an effective interaction with water molecules, and it is difficult for water molecules to overcome the intermolecular forces to disperse and dissolve them. However, in non-polar organic solvents, such as ether, benzene, etc., the solubility is relatively good, and the molecules can interact with non-polar solvent molecules through van der Waals forces to uniformly disperse them.
Again, its chemical properties are basic because it contains active groups such as amino groups. The nitrogen atom in the amino group has lone pairs of electrons, which can bind protons. In an acidic environment, it is easy to react with acids to form corresponding salts. At the same time, hydroxyl groups and other groups are also active and can participate in various substitution reactions. Under appropriate conditions, the hydrogen atom of the hydroxyl group can be replaced by other groups, and many derivatives can be derived. In addition, the unsaturated bonds and other structures in the compound can undergo addition reactions. When a suitable reagent is encountered, the unsaturated bonds can be opened and combined with the reagent molecules to change the structure of the compound. And under the condition of redox, the relevant groups can undergo valence changes and participate in oxidation or reduction reactions, showing rich chemical activities.

I look at what you said about "AMMA (Z) -2- (2-hydroxyquinoline-4-yl) -2-methoxybenzyl-methoxyaminoformyl-methoxycarbamic acid", which is a rather professional chemical substance. However, it is not easy to know its market price range.
Because the market price is often affected by many factors. First, the cost of production. This includes the purchase price of raw materials, the amount of raw materials, the quality and ease of access, all of which will make the price fluctuate. The complexity of the production process is also critical. If exquisite processes, high-end equipment and professional technicians are required, the cost will rise, which will affect the selling price.
Second, the supply and demand of the market. If the demand for this product is strong and the supply is limited, the merchant may raise the price; conversely, if the supply exceeds the demand, the price may be reduced for promotional sales.
Third, the difference in quality. The quality may be different from that produced by different manufacturers, and the price of high quality may be higher.
Fourth, the difference in region. In different places, due to differences in transportation costs, tax policies, etc., the price will also be different.
I have not checked the detailed data, so it is difficult to determine the specific price range. However, if you want to know, you can consult the chemical trading platform, the chemical raw material market, or contact the relevant manufacturers and distributors to obtain a more accurate price range.

Checking "Tiangong Kaiwu", which is a scientific and technological book written by Song Yingxing in the Ming Dynasty, but searching through it, there is no relevant record of "2- (2-hydroxyvaleraldehyde-4-yl) -2-methoxybenzyl-methoxyhydroxylene acetic acid".
Guy "Tiangong Kaiwu" was written hundreds of years ago. At that time, the chemical understanding was very different from today. The complex compounds involved in modern fine organic chemistry cannot be covered. Modern Quality Standards for such compounds have their own system based on modern science and technology and analytical methods. It is often involved in purity detection, and the content of its main components is measured by high performance liquid chromatography, gas chromatography and other instruments. Impurities also need to be accurately determined to clarify the purity geometry. There are physical property indicators such as melting point and boiling point, which help to distinguish its purity and quality. Confirmation of chemical structure is also crucial, and technologies such as nuclear magnetic resonance and infrared spectroscopy are required.
Therefore, if you want to know the "2- (2-hydroxyvaleraldehyde-4-yl) -2-methoxybenzyl-methoxyhydroxylacetic acid" Quality Standard, you should look for modern chemical analysis methods and related industry norms and standard documents, rather than ancient books such as "Tiangong Kaiwu".
