I. [Product Description] 
Br-PEG-Tryptophan (Bromide-Polyethylene Glycol-Tryptophan) is a multifunctional organic intermediate. It combines the high biocompatibility of the PEG segment with the active groups of tryptophan, making it suitable for the synthesis of pharmaceutical intermediates and the modification of polymer materials. The bromide end can serve as an efficient connection site and is widely used in catalyst loading and the preparation of functional materials.
