Used as a key intermediate in the synthesis of functionalized metal-ligand complexes, particularly in catalysis and coordination chemistry. The iodine substituent at the 3-position facilitates halogen transfer reactions and carbon-carbon bond formations through cross-coupling methodologies. Its overall structure enables strong chelation with transition metals, making it valuable in the development of luminescent sensors and redox-active compounds. Commonly applied in electrochemical studies and as a building block for functional materials in supramolecular chemistry. Also utilized in bioinorganic chemistry for modeling metalloenzyme active sites due to its stable metal-binding properties.
