Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other biologically active molecules. Its structure allows for selective functionalization in drug discovery processes, making it valuable in creating analogs for structure-activity relationship (SAR) studies. Commonly employed in cross-coupling reactions such as Suzuki or Heck reactions to introduce the pyrrolopyridine scaffold, which is prevalent in central nervous system agents and oncology therapeutics. Also utilized in the preparation of PROTACs and other targeted degradation molecules due to its compatibility with diverse synthetic pathways.
