I. [Product Description]
Tosyl-PEG-CHO (Tosyl-Polyethylene Glycol-Aldehyde) is a multifunctional organic intermediate that combines the high reactivity of sulfonyl groups with the biocompatibility of PEG chains. It is widely used in the preparation of pharmaceutical intermediates and the modification of polymer materials. Its aldehyde functional group can serve as an efficient coupling site, enabling precise molecular coupling in the presence of a catalyst, which is suitable for the construction of complex molecular structures.
