mPEG5000-amine  (Synonyms: mPEG5000-NH2)

mPEG5000-amine (mPEG5000-NH2) is a class of functionalized polymers composed of a methoxy-terminated polyethylene glycol backbone and a terminal primary amine group. mPEG5000-amine serves as an important intermediate for constructing functionalized nanocarriers, modifying proteins or polypeptides, and developing novel drug delivery systems.

mPEG-amines of different molecular weights are suitable for different research scenarios. For example, low molecular weight (e.g., MW 350-2000 Da) is often used for small molecule coupling or surface modification, while high molecular weight (e.g., MW 5000-20000 Da) is more suitable for prolonging in vivo circulation time or constructing steric hindrance layers.
