Description

General description

An excellent derivative for minimizing aspartimide formation during Fmoc SPPS, including those containing the Asp-Gly sequence. The bulky OBno protecting group offers considerably more protection against the formation of aspartimide-related by-products than the commonly used OtBu and OMpe group.^,
