Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its structure allows for selective functionalization, making it valuable in creating biologically active molecules. Commonly employed in medicinal chemistry for constructing pyridazine-based scaffolds that exhibit antitumor and anti-inflammatory activities. Also utilized in agrochemical research for designing novel pesticides due to its halogen substitution pattern, which enhances binding affinity and metabolic stability.
