Used as a key intermediate in organic synthesis, particularly in the preparation of functionalized polymers and macromolecules. Its iodine functionality allows for further derivatization via cross-coupling reactions, such as Heck or Suzuki couplings, enabling the construction of complex molecular architectures. The tert-butyl ester group provides stability during synthesis and can be easily deprotected under mild acidic conditions to release the corresponding carboxylic acid for conjugation or polymerization. Commonly employed in the development of specialty monomers, drug delivery systems, and functional coatings where controlled reactivity and solubility are required.
