Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in the preparation of bioactive molecules due to its ability to undergo selective functionalization at the bromine site. Commonly employed in cross-coupling reactions such as Suzuki and Heck reactions to construct complex indole derivatives with potential antitumor and anti-inflammatory activities. Also utilized in research settings for the design of novel heterocyclic compounds in medicinal chemistry.
