Propargyl-PEG8-acid has an alkyne group and an acid group. The acid group can derivatize amine-containing molecules in the presence of activators such as EDC or HATU. The alkyne group can react with azides via copper catalyzed Click Chemistry reactions. The PEG units help increase the solubility of the molecule in aqueous environment. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
