Acetoxy group

The Acetoxy group, abbreviated AcO or OAc, is a chemical functional group of the structure CH3-C(=O)-O-. It differs from the acetyl group CH3-C(=O)- by the presence of one additional oxygen atom. The name acetoxy is the short form of acetyl-oxy. An Acetoxy group may be used as a protection for an alcohol functionality in a synthetic route. (Although the protecting group itself is called an acetyl group)) There are several options of introducing an acetoxy functionality in a molecule from an alcohol (in effect; protecting the alcohol by acetylation).
