I. [Product Description]
OPSS-PEG-ASP is a multifunctional organic intermediate. Through the precise coupling of the ortho-pyridyl disulfide bond (OPSS) with aspartic acid (ASP) and combined with the high biocompatibility of polyethylene glycol (PEG), it can serve as an efficient catalyst or pharmaceutical intermediate and is widely used in bioconjugation reactions and the synthesis of polymer materials. Its modular design supports flexible functional modification and it is the core raw material for constructing intelligent delivery systems.
