m-PEG17-acid（Cat No.:I015957）is a monofunctional polyethylene glycol derivative with a methoxy group at one end and a terminal carboxylic acid at the other, linked by a PEG₁₇ chain. The carboxyl group can be activated for coupling with primary amines, hydroxyls, or other nucleophiles, forming stable covalent linkages. The long PEG₁₇ spacer provides excellent hydrophilicity, flexibility, and biocompatibility while minimizing steric hindrance and nonspecific interactions. This reagent is particularly suited for surface modification, bioconjugation, nanoparticle functionalization, and drug delivery systems requiring extended PEG chains to enhance solubility and circulation time.
