Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of cardiovascular and anti-inflammatory drugs. Its structure allows for further functionalization, making it valuable in medicinal chemistry for building pyridazine-based bioactive molecules. Commonly employed in research settings to design compounds with potential hypotensive or vasodilatory effects. Also utilized in agrochemical research for developing novel herbicides and plant growth regulators due to its reactivity and stability in multi-step syntheses.
