Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of cardiovascular and anti-inflammatory agents. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for building complex heterocyclic systems. It is also employed in research settings to explore new reaction pathways in pyridazinone-based chemistry. Due to its bromine substituents, it serves as a versatile substrate for cross-coupling reactions such as Suzuki and Heck reactions, enabling the creation of diverse compound libraries for drug discovery.
