Used in organic synthesis as an intermediate for pharmaceuticals and fine chemicals. The iodo group allows for cross-coupling reactions, such as Suzuki or Heck reactions, enabling the construction of complex aromatic systems. Commonly employed in the development of bioactive molecules, including potential therapeutic agents. Also utilized in materials science for creating organic semiconductors and fluorescent dyes due to its rigid naphthalene backbone. Its reactivity makes it valuable in forming carbon-carbon bonds during the synthesis of advanced intermediates.
