Product Information

• Name: 4,7-Dichloroisatin
• Synonyms: 4,7-Dichloroindole-2,3-dione4,7-Dichloro-2,3-indolinedione
• Brand: Biosynth
• Description: 4,7-Dichloroisatin is an organic compound that is synthesized by ring-opening of oxindole. It is a bifunctional molecule that can be used for the synthesis of other organic compounds. 4,7-Dichloroisatin has been found to be an efficient method for the synthesis of thiazolidinedione derivatives and can be used as a control experiment for this type of reaction. The mechanism for the reaction includes nitroaldol addition to the C=O group, followed by nucleophilic attack on the carbonyl group to form a tetrahedral intermediate. The intermediate then collapses to form a new C=N bond and release acetonitrile.
