I. [Product Description]
OPSS-PEG-Lysines is a multifunctional organic intermediate. Through the efficient coupling property of ortho-pyridyl disulfide (OPSS) with thiol groups and the biocompatibility of polyethylene glycol (PEG), it is widely used in the development of biological materials, the construction of nanocarriers, and catalytic reaction systems. Its core value lies in the controllable cross-linking ability and excellent stability, which is suitable for the preparation of pharmaceutical intermediates and the precise modification of complex molecular structures.
