Product Information

Description	Propargyl-PEG11-O-C1-NHS ester is a PEG linker containing a propargyl group and an NHS group. It is amine-reactive, thus, useful for derivatizing biomolecules with an amine group. The propargyl group reacts with azides via copper-catalyzed azide-alkyne Click Chemistry to form a stable triazole bond. The hydrophilic PEG spacer increases solubility in aqueous media.
Synonyms	Propargyl-PEG12-CH2COO-NHS ester; 2,5-Dioxopyrrolidin-1-yl 3,6,9,12,15,18,21,24,27,30,33,36-dodecaoxanonatriacont-38-ynoate
