I. [Product Description]
SS-PEG-NHS (Disulfide bond-Polyethylene glycol-N-hydroxysuccinimide ester) is a multifunctional organic intermediate that combines the dynamic responsiveness of disulfide bonds, the hydrophilicity of PEG chains, and the high reactivity of NHS esters. It is widely used in fields such as bioconjugation and material modification. Its disulfide bond structure enables reduction-sensitive cleavage, the PEG chain enhances the water solubility of the product, and the NHS ester group can efficiently couple with primary amines. It is a key catalyst or linking unit for the synthesis of complex functional molecules.
