I. [Product Description] 
Br-PEG-SPDP (Bromide-Polyethylene Glycol-Dithiodipyridine Disulfide) is a multifunctional organic intermediate with both high-efficiency coupling and controlled release properties. It is widely used in the synthesis of pharmaceutical intermediates and the preparation of nanomaterials. The bromo group and disulfide bond structure in its molecule can serve as active sites for precise modification. Combining with the hydrophilicity and steric hindrance effect of the PEG chain, it significantly enhances biocompatibility and reaction controllability, and shows unique advantages in the construction of catalytic carriers.
