I. [Product Description]
Br-PEG-OPSS (Bromide-Polyethylene Glycol-O-Pyridyl Disulfide) is a multifunctional organic intermediate that combines the high reactivity of bromide with the controllable cross-linking properties of the OPSS group. As a key component in the synthesis of pharmaceutical intermediates and polymer materials, its adjustable PEG molecular weight endows the product with excellent water solubility and biocompatibility, and it is widely used in the fields of bioconjugation and nanocarrier construction.
