Used as an 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 heterocyclic systems found in bioactive molecules. Commonly employed in cross-coupling reactions, such as Suzuki or Buchwald-Hartwig, to introduce the pyrrolopyridine scaffold into drug candidates. Also utilized in research settings for the preparation of analogs in structure-activity relationship (SAR) studies.
