产品描述

A coupling activator for racemization-free coupling in peptide synthesis; An additive for peptide segment coupling in in reducing the extent of configurational loss at the reactive carboxylic acid residue. Carpino L A etc. works demonstrated that the DIC/HOAt system is more effective in preserving configuration for peptide segment coupling than the analogous DIC/HOBt system

in DMF and DCM. [1]
