Application of 334952-09-9, Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 334952-09-9, name is 2-Oxoindoline-6-carboxylic acid, This compound has unique chemical properties. The synthetic route is as follows.
2-carbonylindolone-6-carboxylic acid (40 g, 0.23 mol) was added to the reaction flask, 200 ml of methanol was added, and the mixture was slowly added dropwise, and the temperature was raised to 60 C by slowly dropping thionyl chloride (32 g, 0.27 mol). The reaction was carried out for 6 hours. After completion of the reaction, the reaction mixture was evaporated to dryness, ground with methanol, filtered and dried to obtain 40 g of 2-carbonylindolone-6-carboxylate in a yield of 93%.
The chemical industry reduces the impact on the environment during synthesis 2-Oxoindoline-6-carboxylic acid. I believe this compound will play a more active role in future production and life.
