Used as an intermediate in the synthesis of nitrogen-containing heterocyclic compounds, particularly in the development of pharmaceuticals. It serves as a building block for pyridine-based derivatives with potential biological activity, including kinase inhibitors and antimicrobial agents. Its hydrazine functionality allows for condensation reactions to form hydrazones, which are valuable in medicinal chemistry and drug discovery. Also employed in the preparation of functionalized nicotinamide analogs for biochemical research.
