Used primarily as an intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. Its structure allows for selective transformations due to the presence of both iodine and carboxylic acid functional groups. Commonly employed in coupling reactions, such as Suzuki or Heck reactions, where the iodine moiety acts as a reactive site for carbon-carbon bond formation. Also utilized in the synthesis of bioactive molecules, including antimicrobial and anti-inflammatory agents. The alpha,beta-unsaturated system enables conjugate addition reactions, expanding its utility in building complex organic frameworks.
