Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of pyridazine-based bioactive compounds. Its structure allows for functionalization at multiple sites, making it valuable in medicinal chemistry for creating analogs with potential antihypertensive, anti-inflammatory, or antimicrobial activity. Also employed in agrochemical research for designing novel pesticides and herbicides due to the pyridazine ring’s favorable electronic properties. Commonly utilized in cross-coupling reactions and nucleophilic substitutions to build complex heterocyclic systems in drug discovery programs.
