Linear monofunctional methoxy PEGs have a functional reactive group at one end of the PEG polymer chain, while the other end is capped with a methoxy group, which can be extensively used for PEGylation of proteins, peptides, oligonucleotides, nanoparticles, bioconjugation, drug delivery and surface modifications.

Huateng Pharma offers high quality linear monofunctional methoxy PEGs with high purity and low polydispersity.

Monofunctional PEGs with molecular weights and functional groups not listed in our online catalog may be available by custom synthesis. Please inquire at sales@huatengusa.com about pricing and availability.
