Key Features and Details
Tris
| SKU | 02194855-CF |
| Alternate Names | Trometamol; Tromethamine; Tris-[hydroxymethyl]amino- methane; THAM; 2-Amino-2-(hydroxymethyl)- 1,3-propandiol; THAM; Tris base |
| Application Notes | Tris has been useful as buffers in a wide variety of biological systems. Uses include pH control in vitro and in vivo for body fluids and in buffering systems for electrophoresis applications. Tris has been used as a starting material for polymers, oxazolones (with carboxylic acids) and oxazolidines (with aldehydes). Tris does not precipitate calcium salts and is of value in maintaining solubility of manganese salts. It can be used for the direct standardization of a strong acid solution; the equivalence point can be determined either potentiometrically or by use of a suitable indicator such as 3-(4-Dimethylamino-1-naphthylazo)-4-methoxybenzenesulfonic acid. It is an auxiliary material in pharmaceutical science. |
