TRIS HCl (tris(hydroxymethyl)aminomethane hydrochloride)

Tris and Tris Hydrochloride have 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). 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 .


The pH values of all buffers are temperature- and concentration-dependent. For Tris buffers, pH increases about 0,03 unit per °C decrease in temperature, and decreases 0,03-0,05 unit per ten-fold dilution.
