I. [Product Description]
OPSS-PEG-PCL is a multifunctional organic intermediate, a triblock copolymer composed of an o-pyridyl disulfide bond (OPSS), polyethylene glycol (PEG), and polycaprolactone (PCL). Its unique structure endows it with excellent self-assembly ability and environmental response characteristics. It can be used as a pharmaceutical intermediate or a catalytic carrier for polymer materials, suitable for constructing intelligent delivery systems and functionalized material platforms.
