Phenylboronic acid or benzeneboronic acid, abbreviated as PhB(OH)₂ where Ph is the phenyl group C₆H₅-, is a boronic acid containing a phenyl substituent and two hydroxyl groups attached to boron. Phenylboronic acid is a white powder and is commonly used in organic synthesis. Boronic acids are mild Lewis acids which are generally stable and easy to handle, making them important to organic synthesis.
