2-Amino-5-bromopyrimidine

2-Amino-5-bromopyrimidine (CAS 7752-82-1), also known as 5-Bromopyrimidin-2-amine or 2-Pyrimidinamine, 5-bromo-, is a high-purity brominated heterocyclic amine intermediate widely used in pharmaceutical synthesis, organic chemistry research, nucleoside chemistry, and fine chemical manufacturing. This compound features a bromine substituent at the 5-position and an amino group at the 2-position of the pyrimidine ring, making it a versatile building block for the development of complex organic molecules and active pharmaceutical ingredients (APIs). As a key intermediate in cross-coupling reactions, nucleophilic substitution, and heterocyclic functionalization, it exhibits excellent reactivity in Suzuki coupling, Buchwald-Hartwig amination, Sonogashira coupling, and electrophilic aromatic substitution pathways. Our product is manufactured under strict quality control standards, ensuring a purity of ≥98%, making it ideal for pharmaceutical manufacturing, medicinal chemistry research, antiviral drug synthesis, and scale-up production. This compound is particularly valuable in the synthesis of pharmaceuticals containing brominated pyrimidine scaffolds, kinase inhibitor intermediates, nucleoside analog precursors, and specialty chemical precursors. As a reliable heterocyclic intermediate from our product line, it serves as an important precursor for constructing functionalized nitrogenous heterocyclic systems in drug discovery and fine chemical development programs.
