I. [Product Description] 
Boc-NH-PEG-Biotin is a multifunctional organic intermediate that combines the high affinity of biotin with the excellent water solubility and stability of the PEG chain. It is widely used in the fields of bioconjugation, material modification, and catalyst support. Its tert-butyloxycarbonyl (Boc) protecting group can be directionally removed, providing a flexible functionalization platform for the synthesis of pharmaceutical intermediates.
