Used as a key intermediate in the synthesis of nitrogen-containing heterocyclic compounds, particularly in pharmaceuticals and agrochemicals. Its reactivity allows for selective cross-coupling reactions, making it valuable in constructing complex organic molecules. Commonly employed in palladium-catalyzed coupling reactions to introduce imidazopyridine scaffolds, which are found in bioactive molecules and drug candidates. Also utilized in materials science for developing organic semiconductors and fluorescent dyes due to its rigid aromatic structure and halogen functionality.
