N-(t-butyl ester-PEG2)-N-bis(PEG3-azide)

N-(t-butyl ester-PEG2)-N-bis(PEG3-azide)

N-(t-butyl ester-PEG2)-N-bis(PEG3-azide) is a branched conjugation reagent The azide groups is very reactive with alkyne such as DBCO, BCN and propargyl reagnet via Click Chemistry. The t-butyl protected carboxyl group can be deprotected under acidic conditions. The hydrophilic PEG spacer increases the hydrophilic properties of the compound. Reagent grade, for research purpose.
