Used as an intermediate in organic synthesis, particularly in pharmaceutical and agrochemical manufacturing. The iodine atom serves as a good leaving group, enabling coupling reactions such as Suzuki or Stille couplings, which are valuable in forming carbon-carbon bonds. The ester group can be hydrolyzed to the corresponding carboxylic acid or reduced to an alcohol, allowing further functionalization. Commonly employed in the preparation of bioactive molecules where a six-carbon spacer with a terminal functional handle is required. Also useful in polymer chemistry for introducing branching or functional end groups.
