Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of vasodilators and cardiotonic agents. It plays a role in the preparation of pyridazinone derivatives, which exhibit biological activity such as positive inotropic effects, making them useful in treating heart failure. Also employed in research for developing new compounds with potential anti-inflammatory and antihypertensive properties. Its structure allows for easy functionalization, enabling use in medicinal chemistry for drug design and optimization.
