I. [Product Description]
Tosyl-PEG-Tryptophan is a multifunctional organic intermediate/pharmaceutical intermediate. Through the synergistic effect of the tosyl (Tosyl) activating group and tryptophan, it can serve as an efficient catalyst carrier or a key linking unit in bioconjugation reactions. Its PEG segment endows it with excellent water solubility and molecular tunability, making it suitable for directional modification and functionalization in complex chemical systems.

II. [Product Details]
