(2-Aminopyrimidin-5-yl)boronic acid（Cat No.:R072961）is a heteroaromatic boronic acid featuring a pyrimidine ring substituted with an amino group at the 2-position and a boronic acid moiety at the 5-position. It is a valuable intermediate in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions for constructing C–C bonds in pharmaceuticals and agrochemicals. This compound enables the functionalization of pyrimidine scaffolds, common in kinase inhibitors and other bioactive molecules. Typically a crystalline solid, it is moisture-sensitive and should be handled under dry conditions with standard protective equipment to ensure stability and safe use.
