Alternate Names N-[Tris(hydroxymethyl)methyl]-2-aminoethanesulfonic acid sodium salt; 2-[(2-Hydroxy-1,1- bis[hydroxymethyl]ethyl)amino]ethanesulfonic acid sodium salt
Application Notes TES has potential for a variety of biological applications. In many culture media that require metal cations, many buffers cannot be used due to chelation or precipitation (citrate or phosphate, for example). TES was found to be beneficial in a study of succinate oxidation. TES is a suitable buffer for epidermal cell growth at pH 7.4 - 7.9 where additional buffering capacity is required.
Base Catalog Number 15246183
CAS # 70331-82-7
Molecular Formula C6H14NSO6Na
Molecular Weight 251.2
Pack Size 250 g
pH Useful pH Buffering Range : 6.8 - 8.2 (Lit.); 9 - 11 (1% aq soln)
pKa 7.5 at 25 °C (Lit.)
Preparation Method A buffer using TES free acid can be prepared by titrating the free acid with 0.5 N sodium hydroxide to the desired pH. Alternatively, solutions of equimolar TES free acid and TES sodium salt can be mixed to attain a buffer of the desired pH. Titrating a solution of TES sodium salt with HCl is not recommended since the resulting solution will contain a half-equivalent of sodium chloride.
Purity ≥90%
