Used as an intermediate in organic synthesis, particularly in cross-coupling reactions such as Suzuki and Heck reactions, to construct carbon-carbon bonds. Its iodine functionality allows for selective metal-catalyzed transformations, making it valuable in the preparation of pharmaceuticals, agrochemicals, and functional materials. The allyloxy group can be further modified or cleaved, enabling versatile derivatization in multi-step syntheses. Commonly employed in the development of liquid crystals, dyes, and bioactive molecules.
