Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of serotonin receptor modulators and other central nervous system agents. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for constructing indoline-based bioactive molecules. Commonly employed in research settings to develop potential treatments for neurological disorders, including depression and anxiety. Also utilized in the preparation of analogs for structure-activity relationship (SAR) studies due to the ease of bromine displacement in cross-coupling reactions.
