PEG (Alkyne)2 denotes a bifunctional polyethylene glycol derivative terminated with alkyne groups, widely utilized in bioconjugation. Synthesized via etherification of PEG diols followed by propargylation, this reagent facilitates copper-catalyzed azide-alkyne cycloaddition (CuAAC). Its generic formula is CnH2n+2Om(C≡CH)2, though specific molecular weights vary by grade.
Store under inert atmosphere at 2-8°C to prevent oxidation or premature polymerization. Avoid direct skin contact and ensure adequate ventilation during handling due to potential irritancy. Not intended for direct human injection without rigorous purification and regulatory approval.
