I. [Product Description] 
SC-PEG-Mal (Succinimidyl carbonate-Polyethylene glycol-Maleimide) is a bifunctional cross-linker, widely used as an organic intermediate/medical intermediate in the site-specific modification and coupling of biological macromolecules. Its maleimide group can achieve thiol-specific reactions, while the succinimidyl carbonate group is suitable for the efficient coupling of amino groups. At the same time, the introduction of the PEG chain significantly improves water solubility and biocompatibility, making it suitable for catalytic reaction systems and complex molecular construction.
