Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) where pyridine derivatives are required. It serves as a building block in the preparation of agrochemicals and functionalized heterocycles due to its reactivity in cross-coupling reactions. Its N-oxide functionality enhances regioselectivity in substitution reactions, making it valuable in fine chemical synthesis. Also employed in research settings for the preparation of ligands and catalysts in organic transformations.
