(5-Aminopyridin-3-yl)boronic acid（Cat No.:R073340）is a heteroaromatic boronic acid featuring a pyridine ring substituted with an amino group at the 5-position and a boronic acid group at the 3-position. This compound appears as a solid, typically off-white, and is widely used in Suzuki-Miyaura cross-coupling reactions for constructing C–C bonds in the synthesis of pharmaceuticals, agrochemicals, and advanced materials. The amino group offers additional functionalization sites, enhancing molecular versatility. Moisture-sensitive and mildly irritant, it should be stored in a dry, inert atmosphere and handled with standard laboratory safety precautions.
