Product Information

Description	Propargyl-PEG5-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-PEG6-CH2COO-NHS ester; 2,5-Dioxopyrrolidin-1-yl 3,6,9,12,15,18-hexaoxahenicos-20-ynoate; Propargyl-PEG6 NHS Acetate; 1-(3,6,9,12,15,18-Hexaoxahenicos-20-ynoyloxy)-2,5-pyrrolidinedione; 2,5-Pyrrolidinedione, 1-[(1-oxo-3,6,9,12,15,18-hexaoxaheneicos-20-yn-1-yl)oxy]-
