To prepare 2-amino-7-isopropyl-5-oxo-5H-chromono [2,3-b] pyridine-3-carboxylic acid, the following method can be followed.
First take appropriate starting materials, such as phenols and pyridine derivatives with specific substituents. Phenols are used as groups to react with reagents containing isopropyl groups under specific conditions to introduce isopropyl groups at specific positions of phenols. In this step, suitable catalysts and reaction solvents are selected to ensure the orientation and efficiency of the reaction. < Br >
Then, the isopropyl-containing phenol derivative and the pyridine derivative undergo condensation reaction. This process may require the assistance of bases to promote the formation of chemical bonds between the two and to construct the basic structure of chromopyridine. During the reaction, parameters such as temperature and reaction time should be strictly controlled to prevent side reactions.
The structure is completed, and then the amination reaction should be carried out. Choose a suitable amination reagent and introduce the amino group at a specific position under appropriate conditions. This step may require a specific reaction medium and accelerator to increase the reaction activity and selectivity.
Finally, through carboxylation reaction, carboxyl groups are introduced at the target position to obtain 2-amino-7-isopropyl-5-oxo-5H-chromono [2,3-b] pyridine-3-carboxylic acid. After each step of the reaction, it is necessary to separate and purify the product, such as column chromatography, recrystallization, etc., to improve the purity of the product. Precise operation and control of conditions in each step of the reaction are the keys to obtaining high-purity target products.

2-Amino-7-isopropyl-5-oxo-5H-chromoeno [2,3-b] pyridine-3-carboxylic acid, this is an organic compound. Looking at its physical and chemical properties, its properties are first mentioned, at room temperature, or in a solid state, but the exact situation is also related to the crystal form and purity.
When it comes to solubility, because the molecule contains both polar carboxyl and amino groups, and non-polar isopropyl and chromoeno-pyridine structures, it may have a certain solubility in polar solvents such as methanol and ethanol, while in non-polar solvents such as n-hexane, the solubility may be very small.
Its melting point is also an important physical property. Although the exact value is not available, many cyclic structures in the structure interact with hydrogen bonds, making its melting point or relatively high. Due to the strong intermolecular force, high energy is required to overcome it before it can cause it to melt.
In terms of chemical properties, carboxyl groups are acidic and can neutralize with bases to form corresponding carboxylic salts. Amino groups are alkaline and can react with acids to form salts. And chromene-pyridine ring system, because it contains multiple unsaturated bonds, can participate in addition, oxidation and other reactions. In case of strong oxidants, the double bonds on the ring may be oxidized, causing structural changes. At the same time, this compound may have certain stability, but under extreme conditions such as high temperature, strong acid, and strong base, the structure may also be damaged.
In summary, the physicochemical properties of 2-amino-7-isopropyl-5-oxo-5H-chromono [2,3-b] pyridine-3-carboxylic acids are determined by their unique molecular structures, and they exhibit different properties under different conditions.

Today I have a question, what is the market price of 2 - Amino - 7 - isopropyl - 5 - oxo - 5H - chromeno [2,3 - b] pyridine - 3 - carboxylic acid. This is a fine chemical, and its price is not static and often changes due to many reasons.
First, purity has a great impact. If the purity is extremely high, it is almost pure, and there are very few impurities, it is suitable for high-end scientific research experiments. It requires a fine and complex purification process, which is expensive and expensive. On the contrary, the purity is slightly lower, contains some impurities, and is suitable for general industrial production and other scenarios, and the price is relatively low.
Second, the market supply and demand relationship is the key factor. If the demand for this product is strong, many pharmaceutical companies and scientific research institutions compete to buy it, but the supply is limited, merchants may raise prices because of it. On the contrary, if the market demand is weak and the supply is abundant, the price may drop for promotional sales.
Third, manufacturers also have an impact. Different manufacturers have different technologies and cost control. Factories with excellent technology and proper cost control may have competitive product prices; those with backward technology and high cost may have high prices.
I checked "Tiangong Kaiwu" all over, but there is no record of the price of this product. Due to the records in "Tiangong Kaiwu", most of them were common industrial and agricultural production technologies and products at that time. The question today is about modern fine chemical products, not all of their era. To know the exact price of this product, you can consult chemical product suppliers and chemical trading platforms to obtain accurate price information.
