Azido-PEG4-Amido-tri-(t-butoxycarbonylethoxymethyl)-methane is a branched PEGylation compound with a terminal azide group and three t-butyl groups. The t-butyl groups can be removed under acidic conditions. The azide group can participate in copper-catalyzed Click Chemistry reactions with alkynes, DBCO and BCN to form stable triazole linkages. The hydrophilic PEG linker increases the water solubility of compounds in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
