Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of cardiovascular drugs and antihypertensive agents. It serves as a building block in the preparation of pyridazine-based compounds that exhibit biological activity, including kinase inhibitors and agents targeting smooth muscle function. Also employed in agrochemical research for the design of novel herbicides and plant growth regulators due to its ability to modulate enzyme activity in metabolic pathways. Its structure allows for easy functionalization, making it valuable in medicinal chemistry for structure-activity relationship (SAR) studies.
