2-Amino-3-(1,2-dihydro-2-oxoquinoline-4-yl)propanoic acid HCl

The chemical structure of 2-amino-3- (1,2-dihydro-2-oxyquinoline-4-yl) propionic acid hydrochloride can be analyzed as follows.
The main structure of this compound is based on propionic acid. The α-carbon atom on the carboxyl side of propionic acid is connected with an amino acid, which is a typical characteristic of amino acids. The β-carbon atom on the other side is connected to a quinoline derivative. The quinoline part is a fused ring structure, which is formed by fusing the benzene ring with the pyridine ring.

To prepare 2-amino-3- (1,2-dihydro-2-oxyquinoline-4-yl) propionic acid hydrochloride, the method is as follows:
First take an appropriate amount of 1,2-dihydro-2-oxyquinoline-4-formaldehyde, placed in a clean reactor, dissolved in an appropriate amount of organic solvent, this organic solvent can be selected dichloromethane, etc., stirred evenly to form a homogeneous solution. < Br >
Prepare another container, mix alanine with an appropriate amount of alkaline substances, alkaline substances such as sodium carbonate, add water to dissolve, and slowly add dropwise to the above-mentioned solution containing 1,2-dihydro-2-oxyquinoline-4-formaldehyde. Control the reaction temperature at low temperature, about 0-5 ° C, because the reaction is more conducive to directional progress at low temperature and reduce the occurrence of side reactions. After adding dropwise, maintain this temperature and stir for a number of times to make the reaction sufficient.
Then, slowly introduce dry hydrogen chloride gas into the reaction system. This step requires careful operation, because hydrogen chloride is corrosive. After an appropriate amount is passed in, a white solid can be seen gradually emerging, which is the preliminary product.
Then the obtained mixture is filtered to obtain a filter cake, which is washed with an appropriate amount of cold organic solvent to remove impurities. Discard the washing liquid, place the filter cake in a vacuum drying oven, control the temperature and vacuum degree, and make the solvent evaporate completely to obtain the pure product of 2-amino-3- (1,2-dihydro-2-oxyquinoline-4-yl) propionic acid hydrochloride. Throughout the operation, strict safety procedures must be followed, and ventilation and ventilation should be paid attention to to prevent the accumulation of harmful gases.

Fu 2 - Amino - 3 - (1,2 - dihydro - 2 - oxoquinoline - 4 - yl) propanoic acid HCl is also a chemical substance. However, its market price range is difficult to determine. The price of this substance is often influenced by many factors.
First, the simplicity of the production process has a great impact on the price. If the production requires exquisite craftsmanship, special equipment, and complicated steps, which consume a lot of manpower and material resources, the cost will be high and the price will rise accordingly.
Second, the availability and price of raw materials are also key. If the raw material is scarce, or difficult to obtain, or its own price fluctuates violently, it will cause the price of the substance to change.
Third, the situation of market supply and demand also affects its price. If the market demand for this product is strong and the supply is limited, the price will rise; conversely, if the supply exceeds the demand, the price will inevitably fall.
Fourth, the purity of the product is also related to the price. High purity, due to the difficulty of preparation and high cost, the price is often higher than that of low purity.
From the perspective of "Tiangong Kaiwu", the price of all things is determined by the trade-off between the difficulty of production, the price of the required materials, and the amount of supply and demand. The same is true for 2 - Amino - 3 - (1,2 - dihydro - 2 - oxoquinoline - 4 - yl) propanoic acid HCl today. Therefore, in order to determine its market price range, it is necessary to carefully observe the dynamics of the chemical market, consult industry experts, or refer to relevant transaction records to obtain a more accurate figure. However, it is difficult to say what the price range is.
