N-(Propargyl-PEG2)-N-bis(PEG3-t-butyl ester) is a 3-arm PEG reagent with a propargyl groups and two t-butyl ester groups. The propargyl group can react with azides via copper catalyzed Click Chemistry reaction to yield a stable triazole linkage. The t-butyl ester groups can be deprotected under acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
