Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of nicotinic acetylcholine receptor modulators. It serves as a building block in agrochemicals for creating novel pesticides due to its halogenated pyridine structure, which enhances bioactivity. Also employed in the preparation of functionalized pyridine derivatives used in medicinal chemistry and materials science. Its aldehyde group allows for easy functionalization via condensation or reduction reactions, making it valuable in multi-step organic synthesis.
