Product Information

Description	Propargyl-PEG2-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-PEG3 NHS acetate; 2,5-Dioxopyrrolidin-1-yl 2-(2-(2-(prop-2-yn-1-yloxy)ethoxy)ethoxy)acetate; 1-(2-{2-[2-(2-Propyn-1-yloxy)ethoxy]ethoxy}acetoxy)-2,5-pyrrolidinedione; 2,5-Pyrrolidinedione, 1-[[2-[2-[2-(2-propyn-1-yloxy)ethoxy]ethoxy]acetyl]oxy]-; Propargyl-PEG3-CH2COO-NHS ester
