5-Bromo-1H-indole-2-carboxylic acid is a crucial intermediate in organic synthesis and is widely used in many fields such as medicine, pesticides, dyes, etc. Its chemical properties are unique and valuable for investigation.
5-Bromo-1H-indole-2-carboxylic acid is weakly acidic, because there is a carboxyl group in the molecule, which can ionize hydrogen ions. In a basic environment, it can react with bases to form corresponding carboxylate. For example, when reacted with sodium hydroxide, 5-bromo-1H-indole-2-carboxylate sodium and water will be formed. < Br >
In the halogenation reaction, the reactivity of the indole ring is changed because the bromine atom has occupied the 5th position of the indole ring. However, other activity checking points of the indole ring, such as the 3rd position, may still occur under suitable conditions, and then the halogenation reaction can occur, and the structure of more complex compounds can be constructed.
Nucleophilic substitution reaction is also an important property. Carboxyl groups can be converted into derivatives such as acyl chlorides and esters through a series of reactions. Taking the conversion to acid chloride as an example, when interacting with thionyl chloride, the hydroxyl group in the carboxyl group will be replaced by the chlorine atom to form 5-bromo-1H-indole-2-formyl chloride. This derivative is an extremely useful intermediate in organic synthesis. It can react with various nucleophiles, such as alcohols and amines, to form esters, amides and other compounds.
In the reduction reaction, the carboxyl group of 5-bromo-1H-indole-2-carboxylic acid can be reduced under the action of a specific reducing agent. For example, using lithium aluminum hydride as a reducing agent, the carboxyl group will be reduced to the alcohol hydroxyl group to obtain 5-bromo-1H-indole-2-methanol.
These chemical properties of 5-bromo-1H-indole-2-carboxylic acid make it a key starting material for the construction of complex compounds in the field of organic synthesis, laying a solid foundation for the creation of new medicines, pesticides and functional materials.

5-% bromo-1H-indole is an important intermediate in organic synthesis. Common synthesis methods include the following:
First, o-nitrotoluene is used as the starting material. First, o-nitrotoluene is brominated, bromine atoms are introduced into the benzene ring at a suitable position, and then the nitro group is converted into an amino group by reduction, and then the ring is closed to form an indole ring under specific conditions to obtain 5-bromo-1H-indole. In this process, the bromination step needs to pay attention to the control of the reaction conditions, because the selectivity of the bromination position is very critical, which affects the purity and yield of the product; the reduction and ring closing steps also need to select suitable reagents and conditions to ensure the smooth progress of the reaction.
Second, aniline compounds and halides are used as raw materials. The nucleophilic substitution reaction between aniline derivatives and bromine-containing halides occurs under the action of bases and catalysts, and then the indole structure is constructed by intramolecular cyclization reaction. The advantage of this method is that the raw materials are relatively easy to obtain, but the reaction conditions are more harsh, and the reaction equipment and operation requirements are higher. The amount of base, reaction temperature and time need to be carefully regulated to ensure that the nucleophilic substitution and cyclization reaction proceed in an orderly manner, and the product yield is improved.
Third, the Foucault reaction strategy is adopted. With suitable aromatic derivatives as substrates, in the presence of catalysts such as Lewis acid, the Foucault acylation reaction occurs with bromoacetyl compounds to generate corresponding intermediates, and then a series of conversion steps such as reduction and cyclization are performed to obtain the target product. In this pathway, the choice and amount of catalyst for Foucault reaction have a significant impact on the reaction selectivity and activity, and the subsequent conversion steps also need to be carefully designed and optimized to achieve efficient synthesis.
When synthesizing 5-bromo-1H-indole, the most suitable synthesis method should be selected according to the actual situation, such as raw material availability, cost, reaction conditions and product purity requirements, etc., and each reaction step should be carefully optimized to achieve the ideal synthesis effect.

The market price of 5-bromo-1H-indole varies from time to time, and also varies according to factors such as supply, demand, and quality in the market.
In today's pharmaceutical market, this product is often an essential material for pharmaceuticals, and its demand is quite wide. If it is of ordinary quality, and the market supply is sufficient, the price may be slightly flat. However, if there are many people who want it, but the supply is limited, the price will rise.
Looking at various markets, the price may vary from a few gold per gram to tens of gold. When blocking trade, the price varies, and sellers often give discounts due to quantity.
Also, the quality is the most important. The price of 5-bromo-1H-indole with high purity must be higher than that of ordinary ones. Because it is used in fine pharmaceuticals and scientific research experiments, the purity requirements are strict, so the price is high.
And the region also affects its price. In prosperous cities, transportation is convenient, and the flow of goods is gathered. The price may be stabilized due to competition. In remote places, the price may be slightly higher due to transportation costs and obstacles to circulation.
Therefore, in order to know the exact price of 5-bromo-1H-indole, it is necessary to check the market in real time, consult the merchants, and measure the supply and demand situation and the quality.
