I. [Product Description]
SS-PEG-PASP (Disulfide bond-Polyethylene glycol-Polyaspartic acid) is a multifunctional organic intermediate with both dynamic responsiveness and biocompatibility. Its core value lies in achieving controllable degradation through disulfide bonds, combining the hydrophilicity of PEG and the carboxyl reaction activity of PASP. It is suitable for polymer material modification, nanocarrier construction, and optimization of catalytic reaction systems, and has important application potential in the development of pharmaceutical intermediates and the synthesis of functional materials.
