Application

BTTAA is a next-generation, water-soluble ligand for the copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC) that dramatically accelerates reaction rates and suppresses cell cytotoxicity. The biocompatibility and fast kinetics of BTTAA are advancements from water-insoluble TBTA and are desirable for bio conjugation in diverse chemical biology experiments.

Ancillary ligands, especially the tripodal ligands such as tris(triazolylmethyl)amines, have been widely used to accelerate the Cu-catalyzed azide-alkyne cycloaddition (CuAAC, a "click" reaction). However, the relationship between the activity of these Cu(I) complexes and their stability against air oxidation and
