2% 2C4% 2C5-trichloro-1H-indole (9CI) is one of the organic compounds. The preparation method is described in detail as follows:
The Fisher-indole synthesis method is the first. This is a classic method. Under the catalysis of acid, phenylhydrazine and its derivatives and aldides or ketones are first formed into phenylhydrazine, followed by [3,3] -migration rearrangement and aromatization to obtain indoles. To prepare 2% 2C4% 2C5-trichloro-1H-indole, phenylhydrazine containing corresponding substituents and suitable aldides or ketones can be selected. For example, 2,4,5-trichlorophenylhydrazine and acetaldehyde are used as raw materials, and the reaction is heated under the catalysis of sulfuric acid or p-toluenesulfonic acid. At first, 2,4,5-trichlorophenylhydrazine and acetaldehyde condensate to form phenylhydrazone, and then, under the action of acid, the intramolecular rearrangement occurs, and the nitrogen atom forms a bond with the adjacent carbon atom. At the same time, a molecule of ammonia is removed. After the aromatization step, the final product is 2% 2C4% 2C5-trichloro-1H-indole. This process requires attention to the reaction temperature and the amount of acid. If the temperature is too high or the amount of acid is improper, it is easy to cause side reactions and affect the purity and yield of the product.
Transition metal catalyzed cyclization Using transition metals such as palladium and copper as catalysts, halogenated aromatics and nitrogen-containing alkenyl or alkynyl compounds are used as raw materials. For example, 2,4,5-trichlorohalobenzene and suitable enamines are reacted in organic solvents such as N, N-dimethylformamide in the presence of palladium catalysts such as palladium acetate, ligands such as tri-tert-butyl phosphine, and bases such as potassium carbonate. The halogen atom of the halogenated benzene is first oxidized and added to the palladium catalyst, then migrated and inserted with the double bond of the enamide, and finally reduced to form a ring, resulting in 2% 2C4% 2C5-trichloro-1H-indole. This method requires precise control of the amount of catalyst, ligand, base, reaction time and temperature to obtain ideal results.
In addition, there are other synthesis paths, such as using indole as the starting material and introducing chlorine atoms through halogenation reaction. However, this approach is difficult to selectively control. Due to the different activities of the indole ring at different positions, it is easy to generate a variety of halogenated isomers. Complex separation and purification steps are required to obtain the target product 2% 2C4% 2C5-trichloro-1H-indole.

I am looking at your question, and I am inquiring about the market price of 2,4,5-trichloro-1H-indole (9CI). However, the price of this chemical often changes due to various reasons, and it is difficult to determine the value.
First, the difference in quality affects the price. Those with high purity have few impurities, and are better in areas with strict purity requirements such as scientific research and pharmaceuticals, and their price is higher; those with lower purity, or used in industrial processes with low requirements, have slightly lower prices.
Second, the supply and demand trend is related to the price. If the market demand is strong and the supply is limited, if a specific industry develops rapidly, the demand for the product increases greatly, or the production process is blocked, and the supply is difficult to continue, the price will rise; on the contrary, if the supply exceeds the demand, the price will decline.
Third, sources and channels also have an impact. Those who come out of a well-known large factory with good quality control may have high prices; while small factory products, although the price is low, the quality may be difficult to guarantee. And the amount of purchase can also cause different prices, and bulk purchases can often be discounted.
Overall, the market price of 2,4,5-trichloro-1H-indole (9CI) ranges from tens to hundreds of yuan per gram. If you want to know the exact price, you should consult chemical product suppliers, distributors, or professional chemical market information platforms to understand the market in real time.
