Application

1-Methyl-1H-indole-2-boronic acid is widely used as a key intermediate in palladium-catalyzed cross-coupling reactions to construct biaryl systems for drug discovery. It serves as a precursor in the synthesis of indole-based kinase inhibitors and serotonin receptor modulators. Researchers also employ it to develop fluorescent probes and organic electronic materials due to its conjugated indole core.
