I. [Product Description]
Benzaldehyde-PEG-Tosyl is a multifunctional organic intermediate that combines the active benzaldehyde group with the highly efficient leaving group Tosyl. The PEG chain enhances its water solubility and biocompatibility. This compound is of great value in the synthesis of pharmaceutical intermediates and the catalytic modification of polymer materials, and is particularly suitable for constructing functionalized polymer carriers and surface modification reactions.
