Description

m-PEG9-acid features a central methoxy-terminated polyethylene glycol chain with a terminal carboxylic acid group, enabling efficient conjugation in bioconjugation workflows. This amphiphilic structure combines solubility and reactivity, facilitating stable linkages in peptide and protein derivatization under standard conditions.

Application

m-PEG9-acid serves as a versatile, bench-stable linker for conjugation and polymer chemistry, enabling efficient coupling to amines and other nucleophiles under standard conditions. Its nine-ethylene glycol units provide enhanced solubility and reduced non-specific binding, while the terminal carboxylic acid facilitates straightforward activation and incorporation into bioconjugates, drug delivery systems, and functionalized surfaces.
