I. [Product Description]
SS-PEG-COOH (Disulfide bond-Polyethylene glycol-Carboxyl group) is a multifunctional organic intermediate. Its core characteristics include the controllable breakage of disulfide bonds, the hydrophilicity of the PEG chain, and the high reactivity of the carboxyl group. This compound has important application values in biological conjugation, surface modification of nanomaterials, and construction of catalytic carriers, especially suitable for scientific research scenarios that require precise control of release or directional coupling.
