N-Tris(hydroxymethyl)methyl-2-aminoethanesulfonic Acid; N-[2-hydroxy-1,1-bis(hydroxymethyl)ethyl]taurine (7CI,8CI); 2-[[2-Hydroxy-1,1-bis(hydroxymethyl)ethyl]amino]ethanesulfonic Acid;|2-[[Tris(hydroxymethyl)methyl]amino]ethanesulfonic Acid; N-Tris(hydroxymethyl)methyl-2-aminoethanesulfonic Acid; N-|[Tris(hydroxymethyl)methyl]aminoethanesulfonic Acid; TES (Buffering Agent)

TES is a biological buffer (zwitterionic) designed by Good, et al. Typically referred to as Good’s Buffer useful in cell culture media formulations. Selection of biological buffer systems should include the following criteria: exclusion by biological membranes, low absorption between 240-700nm, chemically stable, and stable to temperature and concentration changes.
