The substance is called 1-ene-2-amino-3-carboxyindole, and this substance has multiple chemical properties.
From the view of its structure containing alkenyl groups, the alkenyl group is an unsaturated hydrocarbon group, which endows the substance with unsaturated characteristics and can undergo an addition reaction. In case of bromine water, the alkenyl double bond can be broken, and it is added to the bromine elemental substance to make the bromine water fade. This is a typical reaction of olefins. Because the π bond in the double bond has high activity, it is vulnerable to attack by electrophilic reagents.
It contains an amino group, and the amino group is basic. In aqueous solution, amino nitrogen atoms have lone pairs of electrons, which can bind hydrogen ions ionized by water, so that the concentration of hydroxide ions in the solution is relatively high, so it has a certain alkalinity. When exposed to acid, amino groups will react with acid to form salts. If reacted with hydrochloric acid, amino nitrogen atoms combine hydrogen ions to form ammonium ions, and chloride ions combine with them to form corresponding ammonium salts.
Furthermore, this substance contains carboxyl groups. Carboxyl groups are acidic because they can ionize hydrogen ions. In aqueous solutions, carboxyl groups can be partially ionized, releasing hydrogen ions, making the solution acidic. Can neutralize with bases, and react with sodium hydroxide, carboxyl hydrogen ions combine with hydroxide ions to form water, and carboxyl groups form carboxylic salts. In addition, carboxyl groups can also be esterified with alcohols, and react with alcohols to form esters and water under concentrated sulfuric acid catalysis and heating conditions.
This substance is rich in chemical properties due to its containing alkenyl, amino, carboxyl and other functional groups, and may have important applications in organic synthesis, medicinal chemistry and other fields.

To prepare 1-Jiang-2-amino-3-carboxylbenzene, the following methods can be used:
First, the corresponding benzene derivative is used as the starting material. First, take the benzene with the appropriate substituent group, and introduce the amino group through a clever reaction. This may be done by nitrification to add nitro groups to the benzene ring, and then use suitable reducing agents, such as iron and hydrochloric acid, to convert the nitro group into an amino group. The introduction of carboxyl groups can be achieved by oxidation of the side chain. If the side chain of the benzene ring is an alkyl group, the alkyl group can be oxidized to a carboxyl group under the action of a strong oxidant, such as potassium permanganate.
Second, it can be started from other compounds containing nitrogen and carboxyl groups. For example, take a compound containing a carboxyl group and convert it into an intermediate that can react with a compound containing a benzene ring through a series of reactions. Then connect the intermediate to the benzene ring, and then adjust the substituent through a suitable reaction to obtain the target 1-jiang-2-amino-3-carboxylbenzene.
Third, organic synthesis strategies can be used to utilize various condensation reactions. The fragment containing benzene ring and the fragment containing amino group and carboxyl group are selected, and under suitable catalyst and reaction conditions, it is induced to condensate, spliced into the required molecular structure, and then modified and purified later to obtain pure 1-jiang-2-amino-3-carboxylbenzene.
When operating, be sure to pay attention to the precise control of the reaction conditions, such as temperature, pH, reaction time, etc., which have a great impact on the yield and purity of the product. And during the reaction process, various chemical reagents need to be properly disposed of and safety procedures followed to prevent accidents.

I have heard your inquiry about the market price of "1-Jiang-2-Amino-3-Carboxypyridine". The price of this unusual material is determined by many reasons.
First, its preparation is difficult and easy. If the preparation is difficult, the materials used are rare, and the process is complicated, the price will be high. The procurement of raw materials, the specialization of utensils, and the cost of manpower are all manufacturing costs. The cost is high, and the selling price is difficult and low.
Second, the supply and demand of the market is also the main reason. If this product is in high demand in the fields of medicine, chemical industry, etc., but the supply is limited, the demand exceeds the supply, the price will tend to rise. On the contrary, if the demand is weak and the supply is sufficient, the price may decrease.
Furthermore, the quality of the quality also affects its price. Those with high quality, few impurities, and high purity must be liked by everyone, and their price should be high. And those with poor quality, use or limited, the price must not be as good as the high-quality product.
However, I do not know the current market situation, so it is difficult to determine its price. For accurate prices, you can consult chemical raw material manufacturers, pharmaceutical merchants, or check industry information and trading platforms to get real-time market conditions.

1 + - + Jiang + - + 2 + - + carbamoyl + - + 3 + - + carboxyl benzyl The storage conditions are quite exquisite. These things should be placed in a cool and dry place, and they must not be exposed to direct sunlight. The intensity of sunlight may cause changes in its composition and damage its inherent nature.
Furthermore, the storage place and temperature should also be suitable. Under normal temperature, it may be difficult to maintain its quality for a long time, so it is appropriate to place it in a low temperature environment, probably between two and eight degrees. This temperature range can make the product more stable and reduce the risk of deterioration.
At the same time, the humidity of the air also affects it. If the air is too humid, it may absorb moisture, which may lead to deliquescence and damage its structure and properties. It is necessary to store it. When there are good moisture-proof measures, desiccants and other substances can be prepared to maintain the dryness of the environment.
In addition, it is also necessary to pay attention to the cleanliness and odor-free storage. If there are many impurities or odors in the surrounding environment, it may cause pollution and affect its quality and effectiveness. When storing, it is also necessary to pay attention to sealing to avoid excessive contact with air to prevent oxidation and other reactions, to ensure that 1 + - + river + - + 2 + - + carbamoyl group + - + 3 + - + carboxyl benzyl can maintain its original characteristics for a certain period of time for subsequent use.
