Aceturic acid (N-acetylglycine) is a derivative of the amino acid glycine. The conjugate base of this carboxylic acid is called aceturate, a term used for its esters and salts.
Preparation
Aceturic acid can be prepared by warming glycine either with a slight excess of acetic anhydride in benzene,{{cite journal|title = Hydrazide und Azide organischer Säuren. X Abhandlung. 35.
