Descrizione

Descrizione generale

An excellent derivative for minimizing aspartimide formation during Fmoc SPPS of Asp-containing peptides ^[1]. The bulky OMpe protecting group offers considerably more protection against the formation of aspartimide-related by-products than the commonly used OtBu group ^[1,2].
