Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other biologically active molecules. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for constructing pyridazine-based scaffolds. Commonly employed in research settings to design new drug candidates targeting inflammation, cancer, and central nervous system disorders. Also utilized in agrochemical research for developing novel pesticides and herbicides due to its reactivity and stability in multi-step transformations.
