General description
TES sodium salt belongs to the category of zwitterionic buffers that contain ionizable groups of both positive and negative charges. It has a high water solubility and can effectively stabilize pH levels within the physiological pH range of 6.8 to 8.2 over a broad range of temperatures. TES sodium salt is used in the preparation of electrophoresis buffers. It is one of the commonly used Good buffers in biochemistry and molecular biology research.

Metal-ion affinity (formation) constants were determined for two "Good's" buffers, N-tris(hydroxymethyl)methyl-2-aminoethanesulfonic acid (TES) and N,N-bis(2-hydroxyethyl)glycine (bicine). The metal chelates formed undergo loss of an internal ligand (alcohol) proton (bicine) and undergo hydrolysis (bicine and TES) and dimerization reactions (TES). Bicine
