Used as a key intermediate in the synthesis of biologically active compounds, particularly in pharmaceuticals targeting kinase inhibition. Its halogen substitution pattern allows for selective cross-coupling reactions, enabling the construction of complex heterocyclic systems found in drug candidates. Commonly employed in the development of anticancer, antiviral, and anti-inflammatory agents due to its ability to modulate enzyme activity through interactions with target proteins. Also utilized in research settings for the preparation of pyrrolopyridine-based small molecules in medicinal chemistry programs.
