3-(2-{2-[2-(2-Iodoethoxy)-ethoxy]-ethoxy}-ethoxy)-propyne

Bifunctional PEG4-based crosslinker having terminal alkyne and alkyl iodide groups.

Alkyl iodides are among the most powerful alkylators. They alkylate various O-, S-, N-, and C-nucleophiles. This reactive derivative can be used for preparing different molecules with a terminal alkyne group. Terminal alkyne is a versatile synthon participating in Sonogashira coupling and click chemistry reaction.
