High-purity mPEGs, Starting Material for Activated PEGs
Methoxy polyethylene glycol (mPEG) is a starting material of Activated PEGs, SUNBRIGHT® series. NOF is sole worldwide patent holder of high-purity mPEGs and all derivatives. Our mPEGs have advantage of extremely low diol contents among conventional products.
As shown in following graphs, our mPEG (MW 5,000) contains remarkably low level of diol as impurities, besides providing a narrower distribution pattern of molecular weights. The mPEG enables to yield purity and higher activity of Activated PEGs.
