I. [Product Description]
HS-PEG-SGA (Thiol-polyethylene glycol-succinimidyl glutarate) is a highly efficient and multi-functional organic intermediate, which combines the directional coupling ability of thiol groups with the spatial stability characteristics of PEG chains. It is widely used in bioconjugation reactions and surface modification of nanomaterials. As a pharmaceutical intermediate and catalyst carrier, its succinimidyl ester group can achieve highly efficient and specific modification of amino groups, significantly enhancing the biocompatibility and reaction controllability of the composite system.
