It is an important pyrimidine heterocyclic intermediate with amino and bromo active groups. It can conduct substitution, coupling and condensation reactions to build diverse molecular structures. Widely used in synthesis of antitumor, antibacterial and antiviral drugs, improving drug biological activity and target binding ability. Also applied to develop high-efficiency pesticides and biochemical detection reagents. Commonly used in pharmaceutical research, fine chemical synthesis and biomolecular material preparation.

Irritant solid with slight toxicity. Inhalation of dust may cause respiratory discomfort. Wear dust mask and work under ventilation. Prevent skin and eye contact, flush with plenty of water once contacted. Thermal decomposition generates toxic bromide gas. Keep away from high temperature and open flame. Store separately from food and oxidants. Discard waste as hazardous chemicals properly.
