2,5-Dibromopyrimidine

2,5-Dibromopyrimidine (CAS 32779-37-6), also known as Pyrimidine, 2,5-dibromo- or 2,5-Dibromo-1,3-diazine, is a high-purity dibrominated heterocyclic intermediate widely used in pharmaceutical synthesis, organic chemistry research, nucleoside chemistry, and fine chemical manufacturing. This compound features bromine substituents at both the 2- and 5-positions 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 aromatic substitution, and heterocyclic functionalization, it exhibits excellent reactivity in Suzuki coupling, Buchwald-Hartwig amination, Sonogashira coupling, Stille coupling, and selective bromine displacement 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, kinase inhibitor development, and scale-up production. This compound is particularly valuable in the synthesis of pharmaceuticals containing dibromopyrimidine scaffolds, nucleoside analog precursors, heterocyclic kinase inhibitor intermediates, 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.
