Used in pharmaceutical research as a key intermediate in the synthesis of kinase inhibitors, particularly targeting cancer-related proteins such as BRAF and VEGFR. Its bromoindolinyl structure allows for selective cross-coupling reactions, enabling the development of novel anticancer agents. Also explored in the design of serotonin receptor modulators due to structural similarity to tryptamine derivatives. Commonly employed in medicinal chemistry for scaffold modification to enhance potency and metabolic stability.
