Used as a key intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. Its iodine functionality allows for cross-coupling reactions, such as Suzuki or Stille couplings, enabling the construction of complex organic molecules. The ester group can be hydrolyzed or reduced to introduce carboxylic acid or alcohol functionalities, making it versatile for building blocks in medicinal chemistry. Commonly employed in the synthesis of active pharmaceutical ingredients where a sterically hindered, branched chain is required.
