Description:
Tris(hydroxymethyl)aminomethane [TRIS] |
CAS No.: 77-86-1 |
Applications:
TRIS has a pKa of 8.07 at 25 °C, which implies that the buffer has an effective pH range between 7.07
and 9.07. It can be used as acidic gas absorption agent; Titration acid quantity/ material; Current titration
in the determination of protein sulfhydryl group; Paper serum protein electrophoresis separation and
Starch electrophoresis separation of toxins. It also can be used to make surfactants synthesis,
pharmaceutical intermediates, chemical intermediates, organic synthesize intermediates.
