Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of pyridazine-based bioactive compounds. It serves in the preparation of antihypertensive agents and muscle relaxants due to its ability to modulate biological targets such as ion channels and enzymes. Its amide and keto functional groups allow for further chemical modifications, making it valuable in medicinal chemistry for structure-activity relationship studies. Also employed in the design of heterocyclic compounds with potential anti-inflammatory and antimicrobial properties.
