Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of serotonin receptor modulators and other central nervous system agents. Its structure serves as a building block for indole-based bioactive compounds, making it valuable in medicinal chemistry research. Commonly employed in the preparation of analogs for structure-activity relationship (SAR) studies. Also utilized in the production of agrochemicals and functional materials where indole derivatives play a role in enhancing biological activity or electronic properties.
