Application

BIS-TRIS can be used to study biological buffers. BIS-TRIS has been used in a study that synthesized ferritin grafted with temperature-responsive poly(N-isopropylacrylamide) (PIPAAm-ferritin) by a coupling reaction using PIPAAm and ferritin for obtaining stimuli-responsive biomaterials. BIS-TRIS has also been used in a study that synthesized and described the photochemical properties of oligo- ortho –azobenzenes.
