N-(t-Boc-N-amido-PEG10)-N-bis(PEG10-azide) is a very popular PEG reagent containing a terminal Boc-protected amino and two azide groups. The hydrophilic PEG spacer increases solubility in aqueous media. The azide groups can react with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. The Boc group can be deprotected under mild acidic conditions to form the free amine. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
