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.
P 1636 (OTTO) Phenylboronic acid, 97% Cas 98-80-6 - used in organic synthesis cross coupling reactions.Phenylboronic acid is a boronic acid containing a phenyl substituent and two hydroxyl groups attached to boron. Boronic acids are mild Lewis acids which are generally stable and easy to handle, making them important to organic synthesis including numerous cross coupling reactions.
