Specifications
| SKU | 0215246183 |
| 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% |
| Solubility | Very soluble in water (1 M solution - clear, colorless). |
| Usage Statement | Unless specified otherwise, MP Biomedical's products are for research or further manufacturing use only, not for direct human use. For more information, please contact our customer service department. |
