General description

N,N-Diisopropylethylamine, also known as Hünig′s base, is a sterically hindered amine. It is a non-nucleophilic base commonly employed for substitution reactions.

Application

N,N-Diisopropylethylamine may be used in the synthesis of mannosylated ovalbumin peptides.[1]
Proton scavenger used in peptide coupling[2], enolboration[3], Pd(0)-catalyzed alkoxycarbonylation of allyl phosphates and acetates[4], and as a catalyst in vinyl sulfone synthesis.[5]

Features and Benefits

ZerO2® products are rigorously degassed with highly pure inert gas providing solvents and solutions (anhydrous if specified) with very low residual oxygen content.
