Used in organic synthesis as an intermediate for pharmaceuticals and functional materials. Serves as a ligand in coordination chemistry due to the presence of nitrogen atoms in both pyrrole and pyridine rings, enabling metal complex formation. Applied in the development of fluorescent probes and optoelectronic materials because of its conjugated structure and electron-donating properties. Also investigated for biological activity in medicinal chemistry research, particularly in the design of enzyme inhibitors and receptor ligands.
