Applications
2-Amino-5-bromopyrimidine is a high-value disubstituted pyrimidine heterocyclic intermediate containing amino and bromo functional groups on the pyrimidine ring. It features excellent chemical reactivity and can undergo diazotization, nucleophilic substitution, Suzuki coupling, Buchwald amination and condensation derivatization reactions. It is widely used as key building block for antitumor, antiviral, antibacterial and cardiovascular pharmaceutical intermediates, as well as kinase inhibitor fragments and targeted small molecule drug synthesis. It is also extensively applied in medicinal chemistry structure-activity relationship research, custom fine chemical synthesis and new pesticide fungicide and herbicide molecular development.
Safety Information
Irritating to skin, eyes and respiratory tract. Inhalation of dust may cause throat itching, dry cough and respiratory mucosal discomfort; direct eye contact will lead to obvious stinging, redness and conjunctival congestion. Prolonged skin contact may cause dryness, allergy and inflammatory irritation. Avoid dust inhalation, skin adhesion and eye exposure.
