I. [Product Description] 
Biotin-PEG-NHS (Biotin-Polyethylene Glycol-N-hydroxysuccinimide Ester) is a highly active organic intermediate widely used in the fields of bioconjugation and surface functionalization of materials. Its core value lies in achieving efficient and directional conjugation through the NHS ester group. Combined with the excellent water solubility and biocompatibility of the PEG chain, it is suitable for the preparation of pharmaceutical intermediates and the construction of catalyst support systems.
