N-(Propargyl-PEG2)-PEG3-N-Boc is a branched PEG linker with an alkyne group and a t-butyl ester. The alkyne group reacts with azide-bearing compound in coppper catalyzed azide-alkyne Click Chemistry reaction. The Boc group can be deprotected under acidic conditions. The amino group is reactive with carboxylic acids, activated NHS esters, and carbonyls. Reagent grade, for research purpose.
