Used primarily as an intermediate in organic synthesis, especially in cross-coupling reactions such as Suzuki-Miyaura and Heck reactions, to construct biaryl or styrene derivatives. Its iodine functionality allows for selective activation under palladium catalysis, making it valuable in pharmaceutical, agrochemical, and organic electronics research for building complex aromatic structures, including conductive or luminescent materials. The hexyl chain enhances solubility in organic solvents, improving reaction efficiency in non-polar media.
