Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antihypertensive and antiviral agents. Its structure supports the creation of heterocyclic compounds that are active in biological systems. Commonly employed in medicinal chemistry for modifying drug potency and metabolic stability. Also utilized in agrochemicals for the design of herbicides and plant growth regulators due to its ability to enhance bioactivity. Serves as a building block in research laboratories for developing new pyridazine-based compounds with potential therapeutic applications.
