Applications
3-Amino-6-bromopyridazine is an important disubstituted pyridazine heterocyclic intermediate. The bromine atom at 6-position has high activity, easily undergoing nucleophilic substitution, Suzuki coupling, Buchwald amination and condensation reactions. It is widely used as core building block for antitumor, antiviral, antibacterial and central nervous system pharmaceutical intermediates, kinase inhibitors and targeted small molecule drugs. Also applied in medicinal chemistry structure-activity relationship research, custom organic synthesis and pesticide intermediate development.
