Used in coordination chemistry as a versatile bridging ligand due to its dual imidazole groups, enabling the formation of metal-organic frameworks (MOFs) and supramolecular architectures. Its rigid pyridazine core enhances structural stability in polymeric complexes. Commonly applied in the design of luminescent materials and catalysts, where it supports efficient energy transfer and metal center organization. Also investigated for use in sensor systems for detecting metal ions in solution.
