Description

mPEG-Amine (mPEG-NH2, Amino-PEG, Methoxy poly(ethylene glycol)-Amine, Methoxy PEG Amine, Amino functionalized methoxyl polyethylene glycol) is a linear methoxy PEG reagent with a reactive primary amino or NH2 group. Amine can rapidly react with activated carboxyl acid such as NHS ester to form stable amide bonds. Amine can also react with carbonyl such as ketone and aldehyde. mPEG-Amine with MW at 1k or higher appears as white powder and at lower MW (e.g. 550 and 350) appears as white or off-white semi-solid or wax-like due to their low melting/freezing temperature range (e.g. mPEG MW 550 at 15-25 Celsius). mPEG-Amine is in its free amine form.
