Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its structure enables selective functionalization, making it valuable in constructing complex heterocyclic systems found in bioactive molecules. Commonly employed in cross-coupling reactions such as Suzuki or Heck reactions to introduce aryl or vinyl groups, facilitating the creation of potential drug candidates. Also utilized in research settings for the development of novel pyrrolopyridine-based compounds with antiviral and anti-inflammatory properties.
