Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its structure allows for selective functionalization, making it valuable in constructing complex indoline-based molecules. Commonly employed in medicinal chemistry for SAR studies due to the bromo and fluoro substituents, which serve as handles for cross-coupling reactions and influence bioavailability. Also utilized in the preparation of serotonin receptor modulators and other bioactive agents targeting neurological disorders.
