m-PEG4-PFP ester（Cat No.:I044635）is a monofunctional polyethylene glycol (PEG) reagent featuring a methoxy terminus and a pentafluorophenyl (PFP) ester group, connected by a four-unit PEG spacer. The PFP ester is a highly reactive activated ester that efficiently reacts with primary amines to form stable amide bonds, making it ideal for bioconjugation and surface modification. The methoxy group provides inertness at one end, ensuring directional coupling. The PEG4 spacer improves water solubility, reduces nonspecific interactions, and adds conformational flexibility. This reagent is widely used in drug delivery, polymer synthesis, and biomolecular labeling.
