Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of nicotinic acetylcholine receptor modulators. Its iodo functional group allows for efficient cross-coupling reactions, such as Suzuki or Heck reactions, enabling the introduction of various aromatic or heteroaromatic moieties. Commonly employed in medicinal chemistry for constructing complex molecules targeting neurological disorders. Also utilized in the preparation of agrochemicals and functionalized pyridine derivatives for materials science applications.
