I. [Product Description]
OPSS-PEG-Polyacetal is a multifunctional organic intermediate that combines the dynamic reversible cross-linking properties of the ortho-pyridyl disulfide bond with the biocompatibility of polyethylene glycol (PEG). It is widely used in the synthesis of pharmaceutical intermediates and the construction of polymer material catalytic systems. Its polyacetal backbone provides excellent pH-responsiveness, making it suitable for precise control in complex reaction environments.
