Methoxy PEG (mPEG)

Methoxy PEG (mPEG) linkers are a PEG chain with a reactive group at one end, while the other end is capped with a methoxy group. It is available in monofunctional and heterobifunctional forms with reactive groups such as amine, thiol, azide, NHS, maleimide, carboxyl, alkyne, silane, biotin, DBCO, and DSPE. Known for its excellent biocompatibility, hydrophilicity, and low immunogenicity, mPEG is widely used in drug delivery, nanomedicine, tissue engineering, and surface modification.

We supply high-purity polydispersed Methoxy PEGs from gram to 100 kg GMP-grade scale with consistent quality and full analytical documentation—supporting both research and commercial manufacturing.
