HCTU is a coupling reagent with reactity betwwen HBTU and HATU. It is utilized as an affordable, efficient coupling reagent in fast Fmoc solid phase peptide synthesis (CA Hood, G Fuentes, H Patel, K Page, M Menakuru, JH Park, J. Pept. Sci., 2008, 14, 97-101). The electron withdrawing effect of the chlorine atom in HCTU results in more rapid coupling.
