1-(6-Chloropyridazin-3-yl)hydrazine is used as a key intermediate in the synthesis of agrochemical compounds, particularly in the development of herbicides and plant growth regulators. It serves as a building block in agrochemical research due to its reactive hydrazine group and heterocyclic pyridazine structure, enabling the formation of more complex molecules with biological activity. Its derivatives are explored for their potential in crop protection and modulation of plant physiological processes.
