I. [Product Description] 
PS-PEG-ALK (Polystyrene-Polyethylene Glycol-Alkyne) is a multifunctional organic intermediate, combining the rigid backbone of polystyrene with the hydrophilicity and biocompatibility of PEG chains. The terminal alkyne group can be efficiently modified through click chemical reactions. This product is widely used in the synthesis of polymer materials, immobilization of catalysts, and development of pharmaceutical intermediates. It has significant technical advantages, especially in the fields of constructing functionalized nanocarriers and surface modification.
