Used in organic synthesis as an intermediate for pharmaceuticals and bioactive compounds. Serves as a building block in the development of indole-based drugs, particularly in the design of serotonin receptor modulators and kinase inhibitors. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to the presence of both amine and methyl-substituted indole functionalities. Also utilized in the preparation of fluorescent probes and dyes, where the indole core contributes to photophysical properties. Its derivatives show potential in neurological and oncological research.
