I. [Product Description]
SH-PEG-CHO (Thiol-Polyethylene Glycol-Aldehyde) is a bifunctional PEG derivative that combines the high reactivity of thiol (-SH) with the directional coupling ability of aldehyde (-CHO). It is widely used in the synthesis of organic intermediates, modification of polymer materials, and construction of catalyst carriers. Its unique PEG backbone endows the product with excellent water solubility and biocompatibility, making it a core reagent for functional surface modification and nanomaterial assembly.
