I. [Product Introduction]
Biotin-PEG-TS (Biotin-Polyethylene Glycol-Tosylate) is a multifunctional organic intermediate that combines the high affinity of biotin with the excellent solubility of PEG chains. The terminal tosylate group can serve as an efficient coupling reagent and is widely used in the fields of bioconjugation and material modification. This compound is of great value in the preparation of pharmaceutical intermediates, the construction of polymer catalyst carriers, and the labeling of biomolecules.
