Product Information

Description	Propargyl-PEG4-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-PEG5-CH2CO2-NHS; 2,5-Dioxopyrrolidin-1-yl 3,6,9,12,15-pentaoxaoctadec-17-ynoate; 3,6,9,12,15-Pentaoxaoctadec-17-ynoic acid, 2,5-dioxo-1-pyrrolidinyl ester; Propargyl-PEG4-CH2COONHS; Propargyl-PEG5-CH2COO-NHS ester; Propargyl-PEG5-CH2COOH NHS Ester; 1-(3,6,9,12,15-Pentaoxaoctadec-17-ynoyloxy)-2,5-pyrrolidinedione; 2,5-Pyrrolidinedione, 1-[(1-oxo-3,6,9,12,15-pentaoxaoctadec-17-yn-1-yl)oxy]-
