Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of antihypertensive and anti-inflammatory agents. It serves as a building block for nitrogen-containing heterocyclic compounds due to its reactive hydrazine group. Employed in research for the preparation of pyridazinone derivatives, which show biological activity in central nervous system disorders. Also applied in agrochemicals for the formulation of herbicides and plant growth regulators. Its structure allows for easy functionalization, making it valuable in combinatorial chemistry and drug discovery.
