Applications
3-Amino-6-chloropyridazine is a key disubstituted pyridazine heterocyclic intermediate. The 6-position chlorine has high reactivity for nucleophilic substitution, amination and coupling reactions. Widely used as building block for anti-tumor, anti-inflammatory, antibacterial, CNS drug intermediates and kinase inhibitor synthesis; also used in medicinal chemistry SAR study, custom fine chemical synthesis and pesticide intermediate development.
