Used as a key intermediate in the synthesis of liquid crystal materials for display technologies. Its rigid terphenyl backbone and iodo functional group make it suitable for cross-coupling reactions, particularly in Suzuki and Heck reactions, to build complex aromatic systems. Employed in organic semiconductors and optoelectronic materials due to its ability to promote charge transport and thermal stability. Also explored in pharmaceutical research for radiolabeled compounds, leveraging the iodine atom for imaging or therapeutic applications.
