I. [Product Description]
NHS-PEG-ASPN, N-hydroxysuccinimide ester-polyethylene glycol-aspartic acid, is a high-purity organic intermediate with both functions of pharmaceutical intermediate and bioconjugation catalyst. Its unique design with dual reaction sites of NHS active ester and aspartic acid enables precise and controllable molecular cross-linking and surface modification. Coupled with the excellent water solubility and biocompatibility of the PEG segment, it is suitable for constructing modular functional material systems.
