Used primarily as an intermediate in organic synthesis, especially in the preparation of pyrazole-based pharmaceuticals and agrochemicals. Its iodine functionality allows for cross-coupling reactions, such as Suzuki or Heck reactions, enabling the introduction of aromatic or heteroaromatic substituents. The ethoxyethyl group acts as a protecting group for alcohols or carbonyls during multistep syntheses, offering stability under various reaction conditions and can be removed under mild acidic conditions. This compound is valuable in medicinal chemistry for constructing complex molecules with biological activity.
