I. [Product Introduction] 
Fmoc-NH-PEG-SH (Fluorenylmethyloxycarbonyl-amino-polyethylene glycol-mercapto) is a multifunctional organic intermediate that combines the precise deprotection characteristics of the Fmoc protecting group with the biocompatibility of the PEG chain. It is widely used in the synthesis of pharmaceutical intermediates and the construction of catalyst carriers. Its mercapto group (-SH) enables efficient coupling reactions and is suitable for the precise modification of complex molecular structures.
