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 for pyridazine-containing compounds which exhibit biological activity, including vasodilatory and positive inotropic effects. Also employed in research for the preparation of novel heterocyclic compounds with potential therapeutic applications. Its reactivity allows for functionalization at the amino and carbonyl groups, enabling diverse chemical modifications for drug discovery and optimization.
