Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of cardiovascular drugs and antihypertensive agents. It serves as a building block for pyridazine-containing compounds which exhibit biological activity, including enzyme inhibition and receptor modulation. Its structure allows for easy functionalization, making it valuable in medicinal chemistry for drug design and optimization. Also employed in agrochemical research for developing herbicides and plant growth regulators due to its ability to influence metabolic pathways in plants.
