ACES is a zwitterionic buffering agent used in biochemistry and molecular biology that was first selected and described by Good et al. It is a paraacetamide buffer suitable for environments with a pH of 6.1 - 7.5. ACES can be used as a buffer component in cell culture media for use in agarose and polyacrylamide electrophoresis and in isoelectric focusing of proteins. It forms complexes with most common metals, and the formation constant should be taken into account when using such buffers in solutions containing metal ions.

N-(Carbamoylmethyl)taurine can be used to study biological buffers and zwitterionic compounds. ACES has been used in a study to determine the levels of ibuprofen and flurbiprofen in pharmaceuticals by capillary zone electrophoresis.
Purification Methods
