I. [Product Description]
Br-PEG-SH (Bromide-Polyethylene Glycol-Thiol) is a bifunctional PEG derivative that combines the high reactivity of bromo groups with the directional coupling ability of thiol groups. It can serve as an organic intermediate and a catalyst carrier. Its PEG chain imparts excellent hydrophilicity and steric hindrance effects, and it is widely used in the fields of polymer material synthesis and surface modification, especially suitable for constructing composite systems with controllable molecular structures.
