Product Details

N-[N-Fmoc-L-aspartyl(beta t-butyl)]-N-(2,4-dimethoxybenzyl)glycine

The N-Dmb group disrupts hydrogen bonding in the peptide backbone and reduces aggregation. Incorporated into long or difficult peptides, N-Dmb dipeptides can improve peptide yield and purity. When the Dmb protecting group is attached to the amino acid preceeding Asp in a peptide, Dmb blocks aspartimide formation and the side products resulting from aspartimide formation. In SPPS the N-Dmb group is removed with TFA during peptide cleavage from the resin.
