I. [Product Description]
NHS-PEG-poly PASPN-N-hydroxysuccinimide ester-polyethylene glycol-polyaspartic acid is a multifunctional organic intermediate with both high-efficiency coupling activity and controllable molecular structure characteristics. Its core value lies in being a precise cross-linking agent and modifier in pharmaceutical intermediates. Through the NHS ester group, it can achieve site-specific coupling of biomolecules. The PEG segment endows it with excellent water solubility and steric hindrance effect, and the polyaspartic acid module can be expanded into a functional carrier material, which is suitable for the construction of high-value-added catalytic systems.
