Description

Product Detail

mPEG-OH is a linear monofunctional PEG acid reagent containing a methoxy (CH3O)-capped polyethylene glycol with one hydroxyl group. It is one of the most common PEG raw materials for further derivatization or functionalization to prepare other reactive functional groups on PEG.
mPEG-OH has so far been used for various commercial PEGylated drugs, such as PEG-Interferon and PEG-GCSF. And according to public information, mPEG-OH is one of the PEG raw materials for Pfizer's and Moderna's COVID-19 vaccines.

Biopharma PEG offers a wide range of PEG products from lab to commercial scale in both non-GMP and GMP grades. Email at sales@biochempeg.com and start using a superior product for your next product R&D project.
