Used primarily as a building block in organic synthesis, especially in cross-coupling reactions such as Suzuki and Heck reactions. Its iodo functionality allows for efficient metal-catalyzed bond formation, making it valuable in the preparation of pharmaceuticals, agrochemicals, and functional materials. The tert-butyl group acts as a sterically bulky substituent, which can influence regioselectivity and stability in reaction pathways. Commonly employed in the development of liquid crystals and advanced intermediates where controlled substitution patterns are required.
