Fmoc-Asp(ODmab)-OH 98% Min.

Dmab can be removed with 2% hydrazine in DMF generating an indazole which allows the UV-spectrophotometrical monitoring of the cleavage. Conroy et al. used this Asp derivative for the solid-phase synthesis of N-linked glycopeptides.
As Dmab represents an unhindered p-substituted Z-derivative, Asp(Dmab)-containing peptides are prone to base-catalyzed aspartimide formation.
