I. [Product Description]
SH-PEG-Tosyl (Thiol-Polyethylene Glycol-Tosyl) is a multifunctional organic intermediate with both high catalytic activity and biocompatibility. It is widely used in the synthesis of pharmaceutical intermediates and the modification of polymer materials. The thiol group (-SH) in its molecule provides a specific coupling site, and the tosyl group (Tosyl) serves as an excellent leaving group. Combined with the hydrophilicity and steric hindrance effect of the PEG chain, it significantly improves the reaction efficiency and product stability.
