I. [Product Description]
SS-PEG-ALK (Disulfide-Polyethylene Glycol-Alkynyl) is a multifunctional organic intermediate. Its core structure combines the dynamic reversible cross-linking properties of disulfide bonds, the excellent water solubility and biocompatibility of polyethylene glycol (PEG), and the high-efficiency click chemical reactivity of alkynyl groups. This compound is widely used in the preparation of pharmaceutical intermediates, the synthesis of polymer materials, and the field of bioconjugation reaction catalysts, especially suitable for scientific research scenarios that require precise and controllable chemical modification.
