3-Pyridineboronic acid pinacol ester（Cat No.:R055344）is a boronic ester derivative of pyridine, featuring a boronic acid moiety protected as a pinacol ester at the 3-position of the pyridine ring. This compound is widely used in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon–carbon bonds in the synthesis of heteroaryl and biaryl compounds. The pinacol ester offers enhanced stability and ease of handling compared to free boronic acids. Its pyridine core contributes to ligand coordination and electronic versatility, making it valuable in medicinal chemistry, agrochemical development, and material science applications.
