Aceturic acid (N-acetylglycine) is a derivative of the amino acid glycine. Its salts are called aceturates.

Preparation

Aceturic acid can be prepared by warming glycine either with a slight excess of acetic anhydride in benzene,^[1] or with an equal molar amount of acetic anhydride in glacial (concentrated) acetic acid.^[2]
