Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other biologically active molecules. Its hydrazine functionality allows for further derivatization, making it valuable in constructing heterocyclic systems found in drug candidates. Commonly employed in medicinal chemistry research for building pyridine-based scaffolds with potential antitumor, antiviral, or anti-inflammatory activity. Also utilized in the preparation of agrochemicals and functional materials where halogenated pyridines serve as key structural elements.
