4-Pyridineboronic acid（Cat No.:R010564）is a heteroaromatic boronic acid featuring a boronic acid group at the 4-position of a pyridine ring. It is widely used as a versatile building block in organic synthesis, particularly in Suzuki–Miyaura cross-coupling reactions for forming carbon–carbon bonds. The nitrogen atom in the pyridine ring provides additional coordination properties, making it useful in the development of pharmaceuticals, agrochemicals, and advanced materials. Typically appearing as a white to off-white solid, it is soluble in polar organic solvents and water, and offers excellent reactivity under mild coupling conditions.
