Used as a versatile intermediate in organic synthesis, particularly in pharmaceuticals and agrochemicals. It serves as a ligand or catalyst modifier in metal-catalyzed reactions due to its ability to stabilize metal complexes. Employed in the preparation of pyridine-based compounds where selective functionalization is required. Its N-oxide functionality allows for directed ortho-metalation, enabling precise C–H bond activation and subsequent derivatization. Also utilized in the development of specialty materials and functional molecules requiring polar, nitrogen-containing heterocycles.
