I. [Product Description]
OH-PEG-Mal (Hydroxy-Polyethylene Glycol-Maleimide) is a multifunctional organic intermediate that combines the hydrophilicity of the PEG chain with the high reactivity of the maleimide group. As an efficient bioconjugation catalyst, this compound is widely used in protein modification, surface functionalization of nanomaterials, and polymer synthesis. Its customizable molecular weight can precisely meet the solubility and steric hindrance requirements of different systems.
