I. [Product Description]
Biotin-PEG-Tosyl is a multifunctional organic intermediate. It achieves efficient and directional coupling through the tosylate (Tosyl) active group. The biotin (Biotin) integrated in its molecule can specifically bind to avidin-like proteins, and the PEG chain endows the product with excellent water solubility and steric hindrance effect. This compound has important application value in the fields of catalytic reactions and biomolecular labeling, especially suitable for constructing highly stable composite functional materials.
