In organic chemistry, benzoyl is the acyl of benzoic acid, with structure C6H5CO-. It should not be confused with benzyl, which is the radical or ion formed from the removal of one of the methyl hydrogens of toluene (methylbenzene). Whereas a benzyl substituent is commonly abbreviated "Bn", a benzoyl group is in contrast given the symbol "Bz".
Benzoyl is often used as a protecting group in organic syntheses, which can be easily removed by hydrolysis in dilute basic solution.
