Methoxy PEG Alkyne is a functionalized polyethylene glycol derivative featuring a terminal alkyne group and a methoxy cap. It serves as a critical reagent for bioconjugation via copper-catalyzed azide-alkyne cycloaddition (CuAAC). The standard molecular formula is CnH2n+2On+1(CH2)mC≡CH, with CAS No. varying by PEG chain length (e.g., 78659-06-4 for MW 2k).
Store under inert atmosphere at -20°C to prevent oxidation. Handle in fume hoods due to potential irritancy. Not approved for direct clinical administration without purification; strictly for research use only.
