3-Aminophenylboronic acid（Cat No.:L011714）is an aromatic boronic acid featuring an amino group at the meta (3-) position and a boronic acid group (–B(OH)₂) at the 1-position on a benzene ring. This compound is a versatile building block in organic synthesis, particularly in Suzuki–Miyaura cross-coupling reactions, enabling the formation of C–C bonds with aryl or vinyl halides. The amino group adds nucleophilicity and allows for further functionalization, making it useful in medicinal chemistry, materials science, and sensor development. Its dual reactivity supports applications in drug discovery and advanced functional molecule design.
