Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antimalarial and anticancer agents. Its structure supports the creation of complex heterocyclic compounds that interact with biological targets such as kinases and DNA. Also employed in coordination chemistry as a ligand for metal complexes with potential catalytic or antimicrobial activity. Additionally, it serves in materials science for designing fluorescent probes and optoelectronic materials due to its conjugated aromatic system and halogen functionality.
