Applications
2-Amino-5-bromo-4-methylpyridine is a trisubstituted pyridine heterocyclic intermediate bearing amino, bromo and methyl groups. It features high chemical reactivity, readily undergoing nucleophilic substitution, Suzuki coupling, Buchwald amination and structural derivatization. Widely used as core building block for antitumor, anti-inflammatory, central nervous system pharmaceutical intermediates, kinase inhibitor fragments and targeted small molecule drugs; also applied in medicinal chemistry structure-activity relationship research, custom fine chemical synthesis and pesticide intermediate development.
Safety Information
Irritating to skin, eyes and respiratory tract. Avoid dust inhalation, prolonged skin contact and direct eye exposure. Operate in a fume hood with nitrile gloves, safety goggles and dust mask. Keep away from high temperature, open flame and strong oxidants. Store sealed in dry, dark and ventilated conditions.
