Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of nitrogen-containing heterocyclic systems for potential bioactive molecules. It serves as a building block in medicinal chemistry for creating pyridazine-based derivatives that exhibit antimicrobial, antiviral, or anti-inflammatory properties. Its hydrazine functionality allows for easy derivatization, making it valuable in the preparation of Schiff bases and other hydrazone compounds studied for their biological activity. Also employed in research settings to design novel compounds for structure-activity relationship (SAR) studies.
