应用
Tris(hydroxymethyl)aminomethane is used as a buffer in biochemistry and molecular biology laboratories. It is used as a primary standard to standardize acid solutions for chemical analysis. It finds application in cell membranes to increase permeability. As an alternative to sodium bicarbonate, it used in the treatment of metabolic acidosis. It acts as a precursor for the preparation of polymers, oxazolones and oxazolidines.
