I. [Product Description]
This product (Benzaldehyde-PEG-SH) is a multifunctional organic intermediate that combines the electrophilic reactivity of the benzaldehyde group, the excellent water solubility of the PEG segment, and the efficient coupling ability of the sulfhydryl group. It is widely used in the synthesis of pharmaceutical intermediates and the modification of polymer materials. Its unique structural design can serve as an efficient catalyst carrier or molecular bridging unit, significantly enhancing the stability and functional tunability of composite materials.
