THPTA Ligand

THPTA ligand (tris-hydroxypropyltriazolylmethylamine) is a triazole ligand for water based copper catalyzed Click chemistry reactions. This reagent is very well water soluble. It is especially useful for Click chemistry labeling and conjugation of proteins including antibodies, when organic co-solvents are undesirable.
